INSTALLATION AND OPERATION
PUMP PLUMBING
Use only pipe, fittings, 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 1).
2. The proper selection of hose type and size is vital to optimal
performance
Use good quality inlet hose, compatible with the fluids
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 [1.8meters].
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.
4. It is recommended to install strainer of 32 Mesh size
having double flowrate of the pump at the suction side, to
prevent diaphragm failures.
SHAFT ADAPTER KIT INSTALLATION
Order the appropriate shaft kit according to the chart on Spec
Sheet.
1. Mount shaft adapter (Ref. 1A for 9915-KIT1201, Ref 1B for
9915-KIT1202 and Ref. 1B for 9915-KIT1203) onto the pump
shaft and secure with 3 bolts (Ref. 2) and 3 washers (Ref. 3).
2. Mount pump/base assembly securely to prevent movement.
