PULSAR® 25H HYDRAULIC DIAPHRAGM METERING PUMP

PULSAR 25H is a leak-free, hydraulically balanced diaphragm metering pump, engineered for precise dosing and long-term dependability to deliver superior value. It includes 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 25H is commonly used for applications in industries such as chemical processing, petrochemical, oil & gas, water & wastewater treatment, and power.

● Patented hydraulic diagnostic window yields instant visual indication of system over-pressurization, entrained air in hydraulic fluid and diaphragm integrity

● Hydraulic Performance Valve maintains optimum diaphragm position and allows low suction NPIP of 3 psi (0.2 bar)

● Push-to-prime valve allows quick manual priming of the hydraulic system in addition to automatic air bleeding

● Four bolt tie bar design provides ultimate resistance to piping moments and forces

● Three component check valves for controlled rise, assuring proper valve operation, extended valve seat life, and metering accuracy

● Externally adjustable hydraulic by-pass valve protects against over-pressurization

● Manual self-locking stroke length adjustment with resolution of 0.5% for set point accuracy
