Installation
13
Step One: Mounting
This Everflo pump performs best with a flooded inlet. (The pump’s inlet should be located
below the supply water level.) If the pump must be placed above the water supply, suction
lift is not to exceed two feet (0.6m).
CAUTION
NEVER operate the pump dry.
Catastrophic failure will occur. All plunger pumps require
liquid to lubricate the seals and keep them from overheating.
The pump should be located in an area that is dry and provides adequate ventilation.
The pump must be mounted in a horizontal position.
Secure the rubber feet with #10 (M5) fasteners.
DO NOT
compress the feet, doing so will
reduce their ability to isolate vibration/noise. (Note: fasteners are not included.)
Step Two: Plumbing
See table below for port size and recommended hose sizes.
o
Use Everflo quick connect fittings to connect flexible high pressure tubing.
o
Maximum pump operating pressure is 200psi (13.8bar). Outlet hose working
pressure must be rated appropriately.
o
A pressure regulator is included with the pump and must be used.

NOTE:
Everflo does not recommend the use of metal fittings or rigid pipe to plumb the inlet/outlet
ports. Standard plastic threaded fittings are available by calling Everflo Product Support at 1-
800-864-1649.
Tubing should be compatible with the spraying fluid. At least 18" [450mm] length is
suggested to minimize stress on the fitting/ports and reduce noise. Allow for the shortest
possible tubing route and avoid sharp bends that may kink over time.
Installation of a 50-mesh strainer is required to prevent foreign debris from entering the
system. Failures due to foreign debris are not covered under the warranty.
NOTE:
Restrictions on the inlet may cause a loss in performance and shorten pump life. Inlet pressure
must not exceed 30 psi [2.1 bar]
If a check valve is installed in the plumbing, it must have a cracking pressure of no more
than 1 psi [.07 bar].
CAUTION
DO NOT
locate the motor near low temperature plastics or combustible material. The surface
temperature of the motor may exceed 250°F [121
°
C].
CAUTION
Sealers and Teflon tape may act as lubricant causing cracked housings or stripped threads due to
over tightening. Care should be used when applying sealers; it may enter the pump inhibiting
valve action, causing no prime or no shut-off. Failures due to foreign debris are not covered
under the warranty.
