Installation
Pump Plumbing
Use only pipe, ttings, accessories, hose, etc. rated for the
maximum pressure rating of the pump.
1. Always mount pump with oil sight tube in upright position
(See Figure A).
2. The proper selection of hose type and size is vital to optimal
performance.
a. Use good quality inlet hose, compatible with the uids
being pumped and with good elasticity to reduce inlet
water hammer or pulsation. Be sure that hose is not too
rigid but capable of operating at low vacuums without
collapsing. The diameter of the inlet hose should be
at least that of the pump inlet port size and preferably
one size larger if the inlet line is longer than 6 feet [1.8
meters].
b. Use only approved high pressure hose on the discharge
side of pump.
3. Most ports are provided with hose barb connections. Use
good quality hose clamps and tighten them securely.
