Installation

Step One: Mounting
•
This EverFlo pump is self-priming.
•
The pump should be located in an area that is dry and provides adequate ventilation.
•
The pump may be mounted in any position. However, if mounting the pump vertically the
pump head should be in the down position so that in the unlikely event of a leak, fluid will
not enter the motor.
•
Secure the rubber feet with 1/4” fasteners.
DO NOT
compress the feet, doing so will
reduce their ability to isolate vibration/noise.
Step Two: Plumbing
•
See table below for port size and recommended hose sizes. For pumps with female NPT
ports, use plastic male NPT (Tapered pipe thread) fittings to connect flexible high-pressure
tubing to the pump. For pumps with QA ports use EverFlo QA fittings.
Pump Model
Ports
Minimum inlet hose size
Minimum outlet hose size
EF7000
1/2” Female NPT
3/4” (19mm) Inside diameter
3/4” (19mm) Inside diameter
EF7000-QA
QA
3/4” (19mm) Inside diameter
3/4” (19mm) Inside diameter
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.
•
In some cases, the ports may require a suitable thread sealer applied sparingly.
DO NOT
over-tighten, maximum torque is 45 in/lb [5 N-m].
•
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 recommended 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. 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 2 psi [.14 bar].
Step Three: Connect pump to battery or 12V supply
WARNING
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.
