General Safety Information
(continuted)
Maximum water temperature is
140°F.
All positive displacement plunger
pumps must have a safety relief valve
installed on the discharge side of the
pump, this valve could be either an
unloader or regulator and must be of
adequate flow and pressure for the
pump. (This pump has an unloader
already built in).
Adequate protective guards must
cover all moving parts. Perform
routine maintenance on the pump and
components.
Use only components that are rated
for the flow and pressure of the pump,
this would include hose, fittings, safety
valves, spray guns etc.
Special Features
Wet End
Manifold: Forged Brass: Strength
and no porosity – long life. Higher
hydrostatic pressures – safety.
Unloader: Integral trap pressure, fixed
chemical injector. Simple repair using a
cartridge replacement kit. Bolts: Three
bolts, 10mm, grade 8.8.
Valves: Ultra Form Cages: Durable,
strong, and long life. Unique inlet
valve configuration: the valve cage
incorporates the high pressure packing
head ring. Poppets, Seat and Spring:
303 and 400 series stainless steel. Valve
Caps: Machined brass for greater
strength.
Packing and Plungers: High Pressure
Packing: “V” style (D-1) Buna-N (cotton
duct weave base) strong and tightens
under load. Continuously lubricating
for extended life, self lubricating
packing/Plunger guide support ring.
Low-Pressure Seals: “U” cup double

plunger alignment, maximize packing
and seal life. Plungers: Coated ceramic
stainless steel, strong and durable.
The pump includes a plunger shoe to
distribute the additional plunger load.
Drive End
Bearings: Angular contact ball bearing
stabilizes the crankshaft and one thrust
needle bearing absorbs the plunger
load and assures long radial plate life.
All of the thrust plates are made of heat
treated hardened steel for extended
life.
Crankcase: Precision die-cast, large
cooling fins and anodized for maximum
heat dissipation. Sight glass, fill and
drain plugs.
Rear Cover: Precision die-cast, O-
ring sealed. The housing retains the
