Stainless Steel Pumps

Cat Pumps

Cat Pumps offers a range of stainless steel pumps that meet the needs of many industrial applications. There are three materials available: 304, 316, and duplex stainless steel, with a range of flow rates and pressures: 0.5 ~ 240 GPM and 100 ~ 10,000 PSI (1.9 ~ 908 LPM and 6.7 ~ 689 BAR). The stainless steel pumps are highly resistant to corrosive liquids, such as acids and alkalis, and seawater, ensuring a long and worry-free service life.
