DIAPHRAGM PUMP MANUAL
42 & 43 series retains the raw power and pressure of its predecessors, but also can adapt to situations
where huge flow is not needed. Compact but capable, it is a great fit for tight spaces. It also may be
configured with different inlet types, each with their own unique fittings, to be sure that it fits any
application you can find.

INSTALLATION
Materials
1
diaphragm pump with related accessories
2
(at least) pieces of flexible, reinforced hose piping, with collapsing strength of twice the inlet collapsing pressure, hose must be
minimum 1/2" ID(42 series) or 3/4" ID(43 series)
4 stainless steel hose clamps and screws
4 screws to fasten the pump to the mounting surface
1 electrical cutoff switch
1 fuse
1 screwdriver
1 strong cutting implement for tubing
(if desired) Teflon tape or sealant
Setup
1 .The pump may be mounted in any position. If mounted vertically, the pump head should be in the down position to avoid leakage
into the motor casing in the event of a malfunction.
2.Secure the feet, but do not compress them. Overtightening the securing screws may reduce their ability to dissipate noise and
vibration.
3.Intake hose must be minimum 1/2" (13 mm) ID (42 series) or 3/4" (19 mm) ID (43 series) reinforced hose. Main distribution line
from pump outlet should also be 1/2" (13mm) ID (42 series) or 1/2" (13 mm) ID (43 series) with branch and individual supply lines
to outlets no smaller than 3/8" (10 mm).
4. Plumb the system using high pressure (2 x pump rating), braided, flexible tubing to minimize vibration/noise.
