Addressing your chemical dosing pump challenges
Finding the right pump for your application
Selecting a diaphragm metering pump with proper specifications prevents inefficiency, cavitation, and premature failure. Pulsatron offers 10 wetted-end material options—including PVC, PVDF, PEEK, and stainless steel—ensuring compatibility with virtually any chemical. With pressure capabilities up to 300 psi and flow capacities up to 600 gpd, there’s a Pulsatron model engineered for your specific requirements.
Balancing precision with compliance
Our solenoid diaphragm technology delivers precise chemical dosing even as system conditions fluctuate. With turndown ratios ranging from 10:1 to 1000:1 depending on model, and reproducibility within ±2-3%, Pulsatron metering dosing pumps minimize chemical waste while meeting regulatory standards. NSF 61 approval on select models ensures safety for potable water applications.
Streamlining integration and procurement
From back pressure valves and calibration columns to mixers and tanks, Pulsatron’s complete ecosystem ensures component compatibility and simplified procurement. Our pre-engineered accessory options reduce installation time and eliminate compatibility concerns, while standardized mounting patterns allow simple substitution of competitors’ pumps without redrilling.
Technical excellence built into every Pulsatron metering pump
Heavy-duty solenoid assembly for demanding applications
Pulsatron’s fin-cooled solenoid enclosure effectively dissipates heat to maintain consistent pressure handling capability from startup through extreme field conditions. The thermally protected solenoid prevents seizing in high-heat environments with automatic reset functionality, while our automatic vent feature ensures continuous operation without gas binding or pump failure.
Engineered for long-term performance
All Pulsatron models undergo rigorous testing under strict industry standards, guaranteeing flow and pressure ratings meet specifications. With options including manual adjustment, external pacing, 4-20mA control, and microprocessor-based operation (MP Series), Pulsatron pumps deliver the precise control needed for critical applications like pH adjustment, disinfection, and water treatment.
Industry-proven technology and certifications
With over 25 years of engineering excellence, Pulsatron pumps carry essential agency approvals including ETL, ETL Sanitation, CE, and NSF 61 certification for select models. Our advanced Five Function De-gas Valve offers superior handling of gaseous solutions, while our guided ball check valve systems reduce backflow and enhance priming characteristics. Standard accessories on most models include bleed valve assembly, foot strainer, injection valve, and tubing—providing added value and immediate deployment capability.
