HOW TO INSTALL DELLMECO PUMPS?
Self-Priming Application
The suction lift rangemis up to 8 meters. This will vary according to construction materials and application parameters. All data are based upon pumping water at 20°C
SUBMERGED OPERATION
Our pumps can operate under full submersion. The construction materials must be suitable for the surrounding liquid and the outlet must be positioned above the liquid level.
POSITIVE SUCTION HEAD
As a method for completely emptying holding tanks, clarifiers or similar containers. Optimum inlet pressure should be kept at 0.2-0.3 bar.
RECOMMENDED INSTALLATION GUIDELINES
To reduce piping and pump connections stresses, we recommend flexible connections on both the inlet and outlet pipes and air inlet connections. For best results DELLMECO recommends installing the pulsation dampener on the discharge side of the pump.
Without pulsation dampeners
With pulsation dampeners
1) Connect a flow valve and drain valve to the fluid discharge port of the pump.
2) Connect a valve for maintenance to the fluid suction intake port of the pump.
3) Connect a hose to the valve on the suction-port side and the valve of the discharge-port side of the pump.
4) Connect a hose on the suction-side intake and the discharge-port side to the respective vessels.
