Stainless Triplex Plunger Pumps

CAT PUMPS recently introduced two new stainless steel triplex plunger pumps featuring a 316 stainless steel liquid-end for corrosion resistance. The 7CP6111 and 7CP6171 are designed for pumping liquids like seawater in small seawater reverse osmosis installations, demineralized water for misting, or hot water and sanitizers for sterile cleaning systems. The 7CP stainless steel pumps offer the flexibility of either belt-drive or direct-drive bell housing mounting. Both pumps provide a compact, space-saving footprint and deliver 10.5 gpm of up to 2,000 psi.

The 7CP6111 pump (shown here) features a single-shaft, direct drive 1,750 rpm, while the 7CP6171 features a single-shaft belt drive of 1,450 rpm. Preassembled motor pump units are also available with either a 10-hp or 15-hp motor. (
