Grundfos JP 4-47 PM START self-priming pump Cod. 93294161

High efficiency self-priming pump with press control JP 4-47 PM START

Product code 93294161

The Grundfos JP 4-47 START booster consists of a Grundfos JP pump and a pressure manager. The JP 4-47 START offers the convenience of constant water pressure with automatic start and stop, matched to consumption, from the intelligent pressure manager. The pressure switch starts the pump at 1.5 bar, and the pump continues to run as long as there is flow.

The design is robust and constructed of corrosion-resistant materials to ensure a long life. This booster set guarantees optimal self-priming properties, with a suction lift of up to 8 meters. The self-priming pump also ensures stable operation as it can lift liquid from below the inlet level and handle an air-liquid mixture until the pump reaches a fully primed pumping condition.

The JP 4-47 PM START incorporates dry-running protection that automatically stops the pump in the event of a dry run. This reduces the risk of pump damage and reduces maintenance costs. The anti-cycling function stops the pump in time in the event of a small leak in the system or if a tap has not been completely closed. When a cycle occurs, the pump stops and an alarm is displayed. A non-return valve to prevent backflow is already integrated.

The JP self-priming pump has a built-in thermal protection that immediately shuts down the pump in the event of overheating. The air-cooled motor features oversized, sealed, and greased-for-life ball bearings to ensure quiet operation and minimal maintenance.
