SECTION 2

UNPACKING

Pumps are shipped f.o.b. factory and title passes to customer when carrier signs for
receipt of pump. The customer, therefore, must file any damage claims with the carrier.
Carefully examine the shipping crate upon receipt from carrier to be sure there is no obvious
damage to contents. Open the crate carefully, as accessory items fastened to the inside of the
crate may be lost or damaged. Examine all material inside crate and check against packing list
to be sure that all items are accounted for and undamaged.
General Rules
Never connect a rigid pipe to plastic liquid ends; rather, use flexible connections to both
suction and discharge.
Use piping materials that will resist corrosion by the liquid being pumped. Use care in
selecting materials to avoid galvanic corrosion at pump liquid end connections.
Use piping heavy enough to withstand maximum pressures.
Size piping to accommodate peak instantaneous flow. Because of the reciprocating motion of
the pump plunger, pump delivery follows an approximate sine curve with a peak instantaneous
flow pi (3.14) times the average flow. Therefore, piping must be designed for a flow 3.14 times the
pump capacity; this means that a pump rated for 88 gallons per hour requires piping sufficient for
88 gph (333.1 L/hr) 3.14 (or 276) gph (1044.7 L/hr). Please refer to Milton Roy's NPSH calculator,

To minimize viscous flow losses, pipe viscous liquids with line up to four sizes larger
than the pump port.
Remove burrs, sharp edges and debris from inside piping. Flush and blow out all pipe lines
before making final connections to pump.
Provide for pipe expansion when hot liquids are to be pumped. Support piping so that pipe
weight is not placed on the pump. Never spring piping to make connections.
