The C14 motor is three-phase, 60 Hertz, 3450 RPM, pressure is the difference between the pressure at the 230/460 bolts. Corken provides two manual motor inlet of the pump and at the outlet of the pump. starters for models C10, C12 and C13. One is motor- mounted and the other is wall-mounted. -

1. The pump bypass system must be installed. Without this system, the pump has little chance of performing. 2. A Corken B166 bypass valve (a special valve to vent the pump of vapors and to act as a differential relief valve) makes the ideal installation. -

1.5 Pump Foundation—F-Models If misalignment exists, adjust the shims between the pump base and the foundation until exact alignment is accomplished. Every pump deserves a firm, neat concrete foundation (see figure 1.5). There are many ways to construct a foundation, 1.8 Back-up Wrench and the example in figure 1.5 is only a suggestion. -

A light press with a screwdriver may help if the seal assembly does not move back. Pry the seal housing forward with the screwdriver and remove the housing from the pump.

Reinstall all the metal shims, that were removed during the seal seat, we recommend using a plastic handle disassembly, behind the flange of the seal housing.

A magnetic screwdriver is helpful if available. Install all three screws before tightening. Then tighten the screws evenly. Do not over tighten or break the screws.

Rotate the shaft by inserting a screwdriver in the fan guard and rotating the fan blade. If the shaft does not spin freely with one green shim, add the red shim for additional clearance.

Pressure drop caused by restriction in suction line will cause vaporization and cavitation. Yes! Concentric Reducer Eccentric Reducer An eccentric reducer should always be used when reducing into any pump inlet where vapor might be encountered in the pumpage. - Page 46 Appendix H—Aboveground Installation/Piping Instructions Yes! Never locate pump above level of liquid feeding pump. Product must be able to flow by gravity into pump. Always locate pump below tank level ...the lower the better! Since liquefied gases boil when drawn into a pump by its own suction, the pump must be fed by gravity flow to give stable, trouble-free operation.
