This is a triplex [three plunger rods] positive displacement, reciprocating, plunger pump, constructed of 316SS manifolds, 316 SS valve assemblies, solid ceramic plungers and standard NBR [Buna-N] seals and o-rings. This is a hollow-shafted CAT Pump, bolted directly to a CAT Motor, providing easy, compact installation. The motor is wired for universal AC voltage connection. We have selected the most popular pump/motor combinations below for marine reverse osmosis systems.
For marine desalinators, more feed flow means more and better product water. Choose the largest combination that your generator can support. Please keep in mind that startup current draw, even with a capacitor-start motor, is much higher than the full-load current draw.
Please note: These pump and motor assemblies are factory-ordered, and usually take one to two weeks to drop-ship.
NOTE: We offer the 3.5 GPM pump with both 2.0 and 2.5 HP motors. The reason is that while the 2.0 HP motor is lighter and draws less current than the 2.5 HP motor, it is somewhat more expensive.
