RRV Series may be the last replacement pump you ever buy

 Durability and performance are the prime objectives of the RRV Series pressure washer replacement pumps from Water Cannon. In fact, Water Cannon is so confident in this series that CEO Richard Kurtz says they “will surpass the original.”

“What we want to offer is a replacement pump that will hold up to the life of the engine,” Kurtz says. “The package comes complete; there’s virtually no labor involved. It’s been pretested and preset to pressure … they have a volumetric efficiency rating of 93 percent.”

The RRV Series features a compact body design, sized for direct drive on gasoline engines ranging from 270 cc to 440 cc, for medium- to heavy-duty tasks. The replacement pump has a high-strength forged brass manifold, new triplex ceramic plungers with a thicker wall to help prevent thermal shock, stainless steel valves, side-mount valve seat O-rings, high-quality high-pressure seals, two-piece piston guides, large side-cover sight glass, rear-cover oil drain, and forged precision-ground crankshaft.

“It has oversized bearings; that’s key for long life,” Kurtz says. “It has an aluminum crankcase, which helps dissipate heat. And that allows the crankcase life to last as long as the engine.

“The low-pressure seal has a built-in scraper. It helps keep the pump at high performance and keep it from losing water through the seal system. … It’s very common at the beginning of a pump failure that it starts dripping water out of the front seals. This pump really resists that.”

The pump is tested for service life at a maximum performance of 4 gpm at 4,300 psi.

RRV Series pumps are fully rebuildable, tested to over 2,000-hour life. This series fits 1-inch-keyway horizontal engines and includes bolts, oil and vented dipstick.

“Another feature of this particular pump is it can be used with the Hydro-Pulse valve, which allows you to convert a pressure washer pump to a jetter pump,” Kurtz says. “And new for 2016, the connecting rod is designed with 12 percent more load surface.

“It’s a high-quality replacement, so it would be much more durable than a boxed package or something that would be sold mass-merchandised online,” Kurtz says. “Let’s say you were starting a new job, and you knew you were going to put a pressure washer to use in hard labor for four months, replacing the original pump may be a decision that’s looked at before the job starts … (An RRV Series replacement) may be the last pressure washer pump they ever buy.”
