Pump Tanks Chapter 3: Installation 11 of 67
3-4 Installing Separate Tank Ledge Models
Pump tanks from the 2000, 2700, 3700, and 5100 Series are a two-component design with
separate tank and pump ledge assemblies.
These models include a hardware package and assembly drawing located in the information
packet. The tank and pump ledge were temporarily joined together at the factory, so all
components should line up properly in the field.
General guidelines for installation are the following:
• Two-piece models are not designed to be lifted as a unit. Fully and separately support
both tank and ledge assemblies when they are moved.
• Providing a level area for the tank installation will simplify reconnecting the pump
ledge to the tank.
• Floor mounted tanks and ledges are joined together with support plates and the pump
trim. Gravity and mass provide most of the structural integrity.
• Leg-mounted tanks and ledges are joined together with support plates, the pump trim,
and bolts between the facing surfaces of the tank and ledge. Typically, the tank
assembly is lifted and mounted on the four legs first, then the pump ledge is lifted with
a fork truck, and the two remaining legs are attached. Use the center leg bolt holes and
the facing surface bolts to bring together and align the ledge and the tank. See
assembly drawings on pages 59-61for detailed instructions.
• Butterfly valves bridge the gap between the ledge and tank flanges. These butterfly
valves may be shipped loose or mounted to the pump suction connection to the tank.
• The flanges may not always line up as expected due to the tendency of the metal to
move as it cools. Extra effort may be required to help align the flanges to bring the
tank sections together properly.
Caution! Improper handling may also cause movement of the flanges. Be sure the lifting
lugs or forklift holes are used for moving the tank and base. Do not use any of
the piping as a means of moving the equipment into position.
3-5 Installing Optional Equipment
See pages 59 to 63 in the Appendix for assembly details for the tank legs, ladder, and sight
glass.
3-6 Making Electrical Connections
Supply electricity of the voltage, phase, and cycle listed on the serial tag. Pump motor voltage
must be within plus or minus ten percent of the nameplate voltages.
Pump Starters. Pump motor starters may be pre-mounted, shipped loose, or not provided,
depending on the options specified on the order.
On/Off Selector Switch. All pump starters are supplied with an on/off selector switch on the
starter enclosure cover.
