    WSP™ DATA SHEET WSP™ SELF-PRIMER PUMPS WSP-D300_6 Rev. 3 01/09/20 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.

  • Page 43: Pump Connections

    WSP™ DATA SHEET WSP™ SELF-PRIMER PUMPS WSP-D300_6 Rev. 3 01/09/20 3. Pump Connections Accurately align the connecting flange with the pump port before it is tightened. To prevent problems, avoid pulling the pipeline into alignment by tightening the flange bolts and/or couplings. All lines surrounding the pump must be supported independently to alleviate strain on the pump.
