OP-7 Impeller Oil Change Pump - 12V, with Integral Reversing Switch

The OP-7 is a reliable self-priming, reversing, impeller pump for diesel fuel transfer, oil transfer, or water pumping. The pump is ideal for completing oil changes on generators and boat engines.

Flow direction is reversible with the integrated switch, and it can transfer hot or cold oil easily and without mess directly to or from the engine oil pan. This pump is designed for intermittant use.
The OP-7 is the latest version of this pump. It replaces the OP-2, OP-3, OP-4, and OP-6.

Primary changes between the OP-6 and the OP-7 is that the OP-7 has a significantly higher flow rate (7.4 gpm vs. 3.0 gpm), and a greater self-priming height of 5 ft (vs. 3 ft for the OP-6).
The OP-7 also features a better sealed motor housing - rated at IP67 - dust tight and rated for temporary immersion.

The ports on the OP-7 are internally tapped to 3/8" BSPP threads. The outside of the port accepts 3/4" hose. The pump comes with 3/4" male garden hose fittings threaded into the ports.
