Pulsar 25HJ Hydraulic Diaphragm Pump

Pulsafeeder

Pulsar® 25HJ and 25HL are leak-free hydraulic diaphragm pumps, engineered for precise chemical dosing and long-term dependability to deliver superior value. They include exclusive hydraulic diagnostics that provide immediate visual intelligence about pump and system performance. The Pulsar HypoPump® configuration is the ideal choice for sodium hypochlorite or other off-gassing and difficult-to-handle fluids. Pulsar diaphragm pumps are commonly used for applications in industries such as chemical processing, petrochemical, oil & gas, water & wastewater treatment, and power generation.

Hydraulic diagnostic window provides observation of oil condition and proper pump operation saving time troubleshooting
Externally adjustable bypass valve protects the pump from system over-pressurization to quickly adapt to unexpected changes to process conditions
Push-to-purge button allows for on-demand removal of air from pump hydraulics to avoid wasting energy from inefficient pump operation
Hydraulic performance valve maintains optimum diaphragm position and allows low NPIP of 3 psi (0.2 bar)
Four bolt tie bar design provides ultimate resistance to piping moments and forces
Three component check valves for controlled fluid displacement, assuring reliable hydraulic operation
Manual stroke length adjustment with resolution of 0.5% for set point for +/- 0.5% accuracy and optional electronic stroke length adjustment with 5x improved resolution
