2. Mounting
It is critical that you make sure the pump mounting is level for correct
operation of your WSP™ Self-Primer pump. During installation, the
pump may need to be shimmed or supported to eliminate vibration
and create level operating conditions.
Be sure to place the pump in an accessible area that is as close as
possible to the liquid or slurry being pumped.
3. Clearance
Weir Specialty Pumps recommends at least 18-inches of clearance at
the front of the pump’s rear cover to allow easier removal. This also
facilitates access to the pump’s interior. Minimum clearance may be
no less than 10.5-inches to allow the rear cover to be removed easily.
D.
SUCTION AND DISCHARGE PIPING
Discharge elevation increased suction lift and friction losses will negatively
affect pump operation. To avoid a reduction in pump performance, follow the
operating range noted in the Pump Performance Curve diagram located in
Section X of this instruction manual. This will ensure your pump will operate
within a safe operating range and maximize its performance.
1. Materials
You may use hose or pipe for the discharge and suction lines. Be
sure the hose or pipe materials are appropriate for the type of liquids
being pumped. When using a hose for suction, you
must
select the
kind with reinforced, rigid-wall construction to avoid hose collapse
under suction pressure.
When using suction lines, do not use piping couplings as connectors.
2. Configuring the Line
Lines used for suction and discharge must be kept straight to reduce
friction losses.
Using elbows and fittings substantially increases the friction loss.
When elbows are a necessity, use the kind with a long-radius to
reduce the friction loss.
