Brand: Grundfos
Product Code: Grundfos JP 4-47 PM1

The Grundfos JP 4-47 PM1 water dispenser includes a Grundfos JP pump and a pressure switch. JP 4-47 PM1 offers smooth water pressure comfort by starting and stopping automatically according to consumption with the help of a smart pressure switch. The pressure switch starts the pump at 2.2 bar and the pump runs as long as the flow is. Robust construction and corrosion-resistant materials guarantee long life. The water dispenser offers optimum self-sufficiency, with a lift height of up to 8 meters. The self-priming pump also ensures stable operation by being able to lower the level of the liquid inlet and also withstand the mixture of air and liquid until complete venting occurs.

JP 4-47 PM1 includes a dry-running protection that automatically stops the pump when dry running. This reduces the risk of damage to the pump and reduces maintenance costs. The damp start function stops the pump if there is a small leak in the system or the faucet is poorly closed. When a dense start occurs, the pump stops and an alarm is given. The counterflow is prevented by an integrated check valve. The JP pump has an internal thermal shield that immediately stops the pump if it overheats. The engine is air-cooled and rotates on oversized, closed, long-life ball bearings to ensure quiet operation and minimal maintenance.
