Best for bench or small-Scale lab-like dosing needs or hobbyist setups that require portable peristaltic precision. Caution: the lower pressure ceiling may limit high-pressure dosing tasks.
Metering Pump, 40 GPD, 100 PSI
This high-capacity peristaltic pump handles up to 40 GPD at 100 psi, with a polycarbonate body and Santoprene seals. It includes 20 feet of tubing and spare parts for quick maintenance. The product is NSF 50 listed and designed for robust industrial dosing. Best for larger water treatment systems or industrial processes where higher flow is needed.
Who this is best for: operators needing higher daily output without sacrificing reliability. Why selected: higher flow capacity supports larger dosing requirements. Caution: ensure that tubing and seals are compatible with the full range of chemicals used to avoid accelerated wear at elevated flow rates.
Buying Guide
Key considerations when choosing a peristaltic chemical metering pump:
- Flow range and maximum pressure: Match the pump’s 0.8–17 GPD and 100 psi capabilities to your dosing requirements and system backpressure.
- Voltage and power: Ensure compatibility with your electrical setup (common options are 115V/120V or 220V/60Hz).
- Tubing compatibility: Verify Santoprene or other tubing materials for chemical compatibility with the fluids being dosed and operating temperature.
- Head design and adjustability: Adjustable heads allow precise changes in flow without replacing tubing or heads.
- Maintenance and parts availability: Look for units with readily available spare tubing, O-rings, and injection valves to minimize downtime.
- Application fit: For chlorine or other oxidizers, chlorine-resistant tubing and materials are essential. For higher viscosities, verify max viscosity suitability and potential needs for higher head pressure.
- Size and footprint: Smaller bench-top models fit labs and compact setups; larger units suit industrial environments with higher dosing demands.
Frequently Asked Questions
- What is a peristaltic metering pump?
It uses rollers to squeeze a flexible tube, pushing fluid by the tube’s compression to deliver precise volumes per stroke.
- Which pump is best for chlorine solutions?
Look for chlorine-compatible tubing (Sanoprene or similar) and materials rated for oxidizers; many Stenner models offer chlorine compatibility with the proper tubing.
- Do these pumps require special tubing?
Yes. Peristaltic pumps rely on replaceable tubing that is selected for chemical compatibility, temperature, and life expectancy.
- Can I mix different chemicals with a single pump?
Not typically recommended; use dedicated pumps or tubing for each chemical to prevent cross-contamination and compatibility issues.
- What should I consider for installation height and suction?
Keep the pump within a reasonable suction lift (often 25 feet or less) and avoid long vertical runs that could cause priming issues.
- Is a higher GPD rating always better?
No. Choose a GPD that matches your required dosing rate; higher capacity units can often be throttled down, but matching avoids unnecessary complexity.
