PULSAR® PRODUCT SPECIFICATION OVERVIEW

PULSAR® hydraulically actuated diaphragm metering pumps are offered in three sizes:

Model 25HJ pumps are the smallest of the three models – 

Max. Rated Capacity: 210.7 LPH (55.7 GPH)

Max. Pressure: 220 bar (3190 psig)

Temperature rating: 70 °C (158 °F) Composite diaphragm 110 °C (230 °F) Solid Teflon® diaphragm

Wetted Materials: Metal construction: 316SS, HSO*, Alloy 20 or Hastelloy C

Plastic Construction: PVC, PHC* or KYNAR

Connection Types: Threaded: NPT or BSPT

Flanged: ANSI or DIN Flanges

Model 25HL pumps combine the 25HJ gearing with the 55HL drive end, flow capacities greater than the 25HJ, but without the pressure range of the 55HL.

Max. Rated Capacity:445.3 LPH (117.7 GPH)

Max. Pressure: 96.5 bar (1400 psig)

Temperature rating: 70 °C (158 °F) Composite diaphragm 110 °C (230 °F) Solid Teflon® diaphragm

Wetted Materials: Metal construction: 316SS, HSO*, Alloy 20 or Hastelloy C

Plastic Construction: PVC, PHC* or KYNAR

Connection Types: Threaded: NPT or BSPT

Flanged: ANSI or DIN Flanges

Model 55HL pumps are the largest offering in the PULSAR® line – 

Max. Rated Capacity: 440.6 LPH (116.4 GPH)

Max. Pressure: 220 bar (3190 psig)
