• 3-digit LED speed display; Dual-color LED indicators for clockwise (CW) / counterclockwise (CCW) rotation
• Built-in functions: full-speed priming & draining, power-off parameter memory, leakage & overheating protection
• External control: 0–5V / 0–10V / 4–20mA / 0–10kHz analog speed regulation, level-triggered start/stop & direction switching
• Communication: Half-duplex RS485
• Power supply: Wide-range AC 90–260V; Power consumption: ≤30W; IP rating: IP31
• Net weight: 2.5 kg; Overall dimensions: 245 × 155 × 160 mm
• Max flow rate: ≤640 mL/min (official published parameter)
• Compatible pump heads: YZ15, YZ25, DG multi-channel pump heads with various tubing sizes

Practical User Experience Highlights

The 30° inclined panel is designed for ergonomic comfort rather than decorative purposes, effectively alleviating wrist strain during prolonged daily operation. The full-speed priming function greatly simplifies pipeline air evacuation compared to manual filling. Power-off memory is an indispensable feature for unattended overnight cell incubation and continuous biochemical experiments.

2. Industrial Peristaltic Pump: YT600S-1A

Driven by a stepper motor, it delivers superior flow stability at low rotational speeds. Users can switch preset flow modes with one click (calibrated with #82 tubing). Native Modbus protocol is supported via RS485 interface for industrial automation integration.

Key Technical Parameters

• Rotation: 1–650 rpm bidirectional CW/CCW operation; Controlled via rotary knob + physical buttons
• External analog control: 4–20mA / 0–5V / 0–10V
• Power supply: AC 220V ±10%; Power consumption: ≤400W; IP rating: IP31
• Net weight: 15.22 kg; Dimensions: 360 × 240 × 200 mm
• Maximum single-channel flow: ≤13,000 mL/min
• Integrated stainless steel pump heads: YZ35, KZ35 Mainly matched with food & pharmaceutical packaging machinery; can be paired with dispensing controllers for cyclic timed start-stop workflows.

Structural Craftsmanship Advantages

The integrated stainless steel pump head eliminates dead zones for residual liquid accumulation, ideal for hygienic filling applications. Stepper motors maintain far more consistent flow within the 1–50 rpm low-speed range than conventional asynchronous motors, perfectly suited for precise volumetric filling processes.

3. Pneumatic Explosion-Proof Peristaltic Pump: QD600-3A

Powered solely by compressed air, completely eliminating electrical ignition sources for hazardous locations. Explosion-proof marking: Exd I Mb / Exd II BT4Gb

Key Technical Specifications

• Maximum single-channel flow: ≤12,000 mL/min Applicable Industries: Petrochemical, coal mining and other flammable & explosive environments, as well as sites without mains power supply.

Safety Design Logic

The pneumatic motor generates no electric sparks during operation. Combined with the Exd II BT4Gb flameproof enclosure and reliable grounding design, all electrical ignition sources are completely removed from the fluid delivery system. The air service unit can be rotated and locked externally for convenient air pressure gauge reading.

Important Note: The official webpage of QD600-3A incorrectly attached parameter data of the 10-channel syringe pump LSP10-1B (10 μL–10 mL syringe compatibility, flow range 0.001 μL/min–28.135 mL/min, 0.156 μm micro-step resolution, etc.). In accordance with the requirement that company profiles strictly follow official documents and product parameters correspond to dedicated pages, only the native parameters of the pneumatic explosion-proof peristaltic pump QD600-3A are adopted herein; syringe pump data will not be incorporated.

4. Multi-Channel Expansion & OEM Embedded Solutions

• BT100J-1A can be fitted with DG series multi-channel pump heads for parallel micro-volume dispensing
• YT600S-1A supports dual pump head parallel installation for boosted total flow
• QD600-3A allows combination of 1 to 4 sets of YZ35/KZ35 pump assemblies For OEM integration projects, dedicated base-mounted, panel-mounted and embedded drive boards are available, enabling instrument manufacturers to directly integrate fluid modules into electrical control cabinets seamlessly.

Chapter 3: Horizontal Selection Boundaries — When to Switch Product Categories Instead of Upgrading Models

1. For microliter-per-minute flow rates requiring syringe mounting for microfluidic chip experiments: Abandon peristaltic pumps and adopt laboratory syringe pumps (LSP series)
2. For continuous stable single-channel flow of 8,000–13,000 mL/min with media compatible with flexible tubing: YT600S-1A is more cost-effective in terms of electrical control layout than installing two BT100J pumps in parallel
3. For sites filled with flammable vapor, unstable clean power supply or mandatory hazardous area zoning requirements: The QD600-3A pneumatic explosion-proof scheme cuts renovation costs significantly compared to regular electric pumps installed inside external explosion-proof cabinets
4. For highly corrosive media exceeding the compatibility limit of standard tubing materials: Evaluate micro plunger pumps or syringe pumps with PEEK/borosilicate glass fluid paths; avoid forcing peristaltic pumps for long-term operation

Chapter 4: Most Common Procurement Pitfalls & Avoidance Strategies

Pitfall 1: Oversizing pumps based on maximum nominal flow

Peristaltic pumps deliver optimal service life and precision when operated at 30%–70% of their rated maximum flow. The BT100J-1A is rated ≤640 mL/min; continuous operation at 600 mL/min will drastically shorten tubing lifespan and degrade flow repeatability. Always reserve a 30%–50% flow margin for actual working conditions.

Pitfall 2: Misclassifying tubing as spare accessories rather than consumables

Service life reference: Silicone tubing lasts 800–1000 hours under moderate working conditions; PVC tubing only lasts 200–300 hours. Failure to specify spare tubing sizes (#13, #25, #82 etc.) in purchase orders will lead to urgent production line downtime awaiting supplementary deliveries.

Pitfall 3: Only confirming "explosion-proof certification" without verifying exact explosion-proof grade

QD600-3A carries Exd II BT4Gb rating, suitable for IIB temperature class T4 environments. It cannot be directly applied to IIC hazardous areas (hydrogen-containing atmospheres). For pneumatic explosion-proof pumps, air source drying and oil removal must also be configured; otherwise premature pneumatic motor wear will occur.

Pitfall 4: Undefined external control signal types in formal contracts

BT100J-1A supports four external control signal formats: 0–5V / 0–10V / 4–20mA / 0–10kHz; YT600S-1A supports the first three types exclusively. Mismatched PLC module types will require on-site rewiring and debugging delays.

Pitfall 5: Using overall pump dimensions for embedded OEM design

Complete pumps include outer casings and carrying handles; embedded integration requires base mounting hole layouts and drive board power consumption parameters. Failure to obtain official OEM drawings in advance results in irreversible panel cutting and structural rework later.

Chapter 5: Procurement Guide for Direct Factory Sourcing from Baoding Production Base

1. Verify Certificate Applicant Entity: Confirm that RoHS, CE and explosion-proof certificates are issued under the name of Huiyu Weiye (Beijing) Fluid Equipment Co., Ltd., not the parent group company or trading intermediaries.
2. Request On-Site Production Verification: The 832 ㎡ Baoding workshop and 46-member Beijing team (14 technical staff) are verifiable; pure trading companies cannot provide real-time in-production workshop footage.
3. Sign Working Condition Confirmation Form Prior to Sampling: Finalize seven core parameters before prototype development: fluid medium, operating flow range, backpressure, pump head material, tubing specification, communication protocol (RS485/Modbus/analog), installation method (complete unit / OEM base mount / panel mount). Any omitted item will trigger hardware & software revisions post-sampling.
4. Confirm Lead Time for Wearing Parts: Check delivery cycles of consumables including tubing, pump rollers, sealing rings and drive boards. Stock availability at the Baoding factory plus Beijing headquarters delivery radius directly determines production downtime duration during maintenance.
5. Evaluate End-to-End Customization Capability: Prefer suppliers capable of full-chain delivery including scheme design, structural development, software/hardware programming, finished assembly and system integration. Manufacturers able to supply Modbus register tables and communication frame examples during sampling are far more reliable than those only providing PDF operation manuals.

Chapter 6: One-Sentence Recommendation for the Three Flagship Models

1. BT100J-1A: Ideal for bench-top micro-volume dispensing in university labs and testing institutions; select this model if you require a 30° ergonomic panel, power-off parameter memory and RS485 communication.
2. YT600S-1A: Optimized for stable high-flow delivery (up to 13 L/min) on food & pharmaceutical packaging lines; the stainless steel integrated pump head and native Modbus support make it perfect for automated equipment embedded integration.
3. QD600-3A: The optimal pneumatic intrinsically safe solution for petrochemical, coal mining and non-mains powered explosive hazardous areas with Exd II BT4Gb explosion-proof certification.

Frequently Asked Questions (FAQ)

Q1: The BT100J-1A laboratory pump is rated ≤640 mL/min; what is the recommended daily operating flow range?

A: It is advised to keep routine working flow within 200–450 mL/min (mid-speed range), which balances silicone tubing service life and flow repeatability. Long-term full-load operation at 640 mL/min accelerates silicone tube fatigue and permanent deformation.

Q2: Can the YT600S-1A industrial peristaltic pump be directly connected to a DCS distributed control system?

A: Yes. It is equipped with RS485 interface compatible with Modbus protocol, while retaining 4–20mA / 0–10V analog external control. Request the official register address table, default baud rate and parity check parameters before docking to avoid repeated debugging of DIP switch settings and communication frame formats.

Q3: The QD600-3A pneumatic explosion-proof pump has no electrical components; how is remote communication and control realized?

A: The pneumatic motor itself contains no electronic control circuits. To achieve remote start/stop and direction switching, an external pneumatic solenoid valve manifold (air signal or flameproof solenoid valves) must be configured. RS485 digital communication is not available on the native pneumatic unit; do not confuse it with electrically driven peristaltic pumps.

Q4: Are tubing sizes interchangeable between BT100J-1A and YT600S-1A from the same manufacturer?

A: No interchange is allowed. BT100J-1A uses small-bore tubing matched with YZ15/YZ25/DG pump heads (#13–#25 sizes); YT600S-1A adopts large-bore tubing for YZ35/KZ35 pump heads (#73, #82 sizes). Mismatched tubing cannot be fully compressed, resulting in liquid leakage and unstable flow delivery.

Q5: For small-batch OEM sampling projects, what are the general charging rules and production lead times at manufacturers like Huiyu Weiye?

A: The company accepts both small and mass orders for standard pumps and embedded OEM/ODM products per official capacity statements. The workflow is as follows: confirm the Working Condition Confirmation Form and embedded drive board dimensional drawings first, then negotiate sampling fees and arrange production at the Baoding workshop. For mass production, prioritize verifying lead times of stocked components (pump heads, drive boards, tubing) rather than merely comparing unit prices.
