Receiving

Our shipping container has been specifically designed to prevent transit damage. However, upon receipt of the shipment, note IMMEDIATELY on the freight bill and bill of lading any damage or shortage. Check carefully to make sure that all equipment has been received and is in good condition. Shortages must be reported to Wastecorp. Pumps and the freight carrier within SEVEN (7) days.

Caution: Do not turn speed control wheels on variable speed drives unless the motor is running.

Recommended Precautions
a) Avoid system pressures that may exceed one and a half times the operating point selected from the pump performance curve.

b) Should the fluid temperature rise more than 50°F above ambient, expansion joints must be installed on both the suction and discharge ports to relieve any stress on the pump casing.

c) All electrical wiring of the pump installation must be done by a licensed electrician who will observe all national and local electrical codes. All motors require a magnetic starter with current over-load protection.

d) No modifications, additions or deletions should be made to the pump, without prior approval of the factory.

e) In systems where shock wave pressures may be generated, protective devises such as check valves/gate valves, etc must be installed on discharge line to prevent shock pressures from entering the pump casing.

f) In sewage systems containing discharge check valves, gate valves, etc., pump will not prime against a closed valve. Check the discharge valves making sure they are open before attempting to start pump. If there is a possibility of air being entrapped in the pump casing, install an automatic venting device to bleed off the air.

g) Plunger pumps are designed primarily for sewage plants. Consult the factory before pumping other fluids.

h) Drain casing completely when servicing pump handling volatile or harmful liquids.

i) Do not use in a combustible atmosphere.

j) Make periodic check of the tightness of suction and discharge pipe, drain, filler plug and pump gaskets. Operation should not proceed until all of the above items have been checked and are tight.

k) After servicing the pump, always install the coupling guards, belt guards and other safety devices as originally found prior to disassembly.

l) A plunger pump is a positive displacement pump. Do not operate with a closed discharge. Operating with a closed discharge may result in damage to unit and/or personal injury.
