SEAFLO 42-Series Water Pressure Diaphragm Pump w/ Internal Bypass - 12V, 3.0 GPM, 55 PSI
Meet our newest addition to our diaphragm pumps: the 42 series. UL 778 & CSA 22.2 Certified. It retains the raw power and pressure of its predecessors, but also can adapt to situations where huge flow is not needed. Compact but capable, it is a great fit for tight spaces. It may also be configured with different inlet types, each with their own unique fittings to be sure that it fits any application you can require. It also features an internal bypass to reduce pump cycling. No accumulator tank needed! Our 42-Series will perform optimally under both high flow and low flow. It also features self-priming and priming up to 6 vertical feet while operating quietly during any application. This pump is capable of running dry and even contains a built-in check valve. Lastly, as will all SEAFLO products, it comes with a 4-Year Limited Warranty!
**PLEASE NOTE: On delivery, this pump may rarely have small amounts of residual water left in it. This is due to the rigorous testing the pump goes through for quality assurance and to comply with UL and CSA standards. This is not an indication of a used pump**
