PULSAR Models & Ratings

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

Model 25HJ pumps offer are the smallest of the three models. The product covers applications from 1.86 LPH @ 220 bar (0.49 GPH @ 3190 psig) to 210.7 LPH @ 9.8 bar (55.7 GPH @ 142 psig).

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. This product is suitable for applications from

Model 55HL pumps are the largest offering in the PULSAR line with capacities from 3.9 LPH @ 220 bar (1.03 GPH @ 3190 psig) to 440.6 LPH @ 10.4 bar (116.4 GPH @ 150 psig).
