Durability and performance are the prime objectives of the RRV Series Pumps

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.”

Triplex plunger pumps are the most common types of pumps used in the pressure washer industry

 Triplex plunger pumps are the most common types of pumps used in the pressure washer industry.  The majority of these pumps have solid ceramic plungers or pistons that move the water through the pump and hold pressure created by the nozzle restriction at the end of the spray wand.  These ceramic plungers are very hard and make an excellent seal for high pressures but are not indestructible.  Ceramic plungers can become brittle when the pump is run without water, causing thermal shock.  Thermal Shock occurs when the ceramic plungers are heated due to the friction of the dry plunger moving against the pump seals from lack of water to the pump. The introduction of cool water to the heated plunger will cause a crack or cracks usually running the length of the plunger.  The cracked plunger then allows water to leak past the seals and can be visible by a water leak between the manifold and crankcase of the pump or by turning the oil in the crankcase a milky color due to the emulsification of the oil and water mixture.  This will cause a lack of lubrication then overheating, then, catastrophic failure such as thrown connecting rods etc. 

The typical scenario might be as follows:  One attaches the garden hose to the pressure washer, then the high pressure hose to the machine; one starts the machine expecting water to come spraying out,  then one realizes after a minute or two, that the water is not turned on.  One then turns on the water to the running pump with heated plungers causing the plungers to break and leak.  Always have water flowing to your pump before start up.
