nut is incorporated with a wash ring can be ordered on model Q5010. This is screwed into and out of
the cylinder barrel in the same way as a normal retaining nut. When internal and external o–rings are
added to this wash ring, a chamber is formed called the wash area, as shown in Figure 7-6 below. The
wash area allows residue to be washed off the piston to prevent a buildup of corrosive residue.
Wash areas are not necessary except in special circumstances, such as when very corrosive fluids are
pumped. Wash areas are NOT normally needed for pumping brine.
Wash Ring Option
Holes with fittings are located on the top and bottom of the pump cylinder for fluid to flush through the
wash area. When installing plumbing to these holes, the fitting on the bottom of the pump cylinder
should be used as the fluid inlet and the fitting on the top should be used as the fluid outlet so that
trapped gas can escape.
An active wash area is one where both pairs of o-rings are installed and fluid is used regularly to rinse
the piston. An inactive wash area is one without the internal and external o-rings. Do not leave any of
the o-rings in the wash ring if the pump system is used without any fluid circulating through the wash
area and around the piston. This situation will cause the o-rings to abrade, creating debris that can cause
seal leakage. If your Q5000 Pump Cylinder includes a wash area option, your Spare Parts Kit will also
include replacement o-rings.
