3. Installation
Pump installation site should provide easy access for routine maintenance and protect the pump
from environmental elements and from leaks or drips from nearby process equipment. See
Figure 2 for typical installation diagram.
o Bolt the pump motor down firmly to mounting surface. Provide for air movement and circulation over electric
motor to enhance proper cooling.
o While looking at the pump from the magnetic drive end, the suction port is to the right when the pump drive
shaft rotates clockwise and is located below the ports. Reversing drive shaft rotation reverses flow and thus
suction and discharge ports. Since the Eclipse Standard/Eclipse Hypo series pumps can be installed both
vertically and horizontally, it is very important to verify proper motor rotation before final piping is
established.
o When installed horizontally, make sure the pump housing drain is on the bottom of the pump. If the pump is
installed with the drain facing upwards, the rotation of the motor will be incorrect and either needs to be
reversed or the pump orientation corrected. Reference the pump drawings in Section 18 of this manual for
drain location.
o Installation of vacuum or pressure gauges in the suction and discharge piping is recommended to properly
monitor system operation.
o Keep suction piping system short and straight to minimize friction loss to the pump. Make sure that the pump
will not run dry. Flooded suction or gravity fed fluid to pump inlet is generally preferred.
o Use only full-bore ball valves or gate valves in the suction piping. If suction strainers are used, size them to
minimize pressure drop and select those of a type that are easily cleaned and maintained.
o Arrange all suction piping and fittings to prevent formation of air pockets. Make sure all joints are airtight.
o Flush and blow out all suction lines prior to mating to pump. Use nipples and unions, for ease of maintenance.
