Vertical Multistage Booster PumpsInline design allows pump to be installed in a horizontal plane, where suction and discharge connections are in the same plane and have the same pipe sizes. Closed stainless steel impeller with silicon carbide, stainless steel, and EPDM seals. Pumps feature high-pressure performance at low flow, making them suitable for use in pressure-boosting systems, boiler feed applications, ultra filtration and reverse osmosis system. Compact size allows installation in tight spaces.
