ESPA PRESSDRIVE 2E pressure switch

The ESPA PRESSDRIVE 2E electronic pressure controller is a modern flow-control unit designed for the automatic operation of pumps in water supply systems, irrigation, watering, and domestic water networks. The device combines the functions of a pressure switch, check valve, pressure gauge, and multiple protection systems, eliminating the need for additional components.

Purpose and functionality

PRESSDRIVE 2E automatically starts the pump when water demand appears and stops it when there is no flow, ensuring stable system performance and preventing hydraulic shocks. The unit provides protection against dry running, excessive suction height and operating with a closed valve — the main causes of overheating and pump failure.

Structural features

▪️Flow-through body with inlet and outlet connections.
▪️Built-in pressure and flow sensors, check valve, pressure gauge and water-hammer damper.
▪️Electronic control board with LED status indicators.
▪️Radial layout of inlet/outlet ports at a 90° angle.
▪️Quick-release threaded connection on the inlet and threaded outlet connection.

Advantages of the PRESSDRIVE 2E model

▪️Full automation of pump operation without additional equipment.
▪️LED indication: power on, pump running, protection triggered.
▪️Intelligent auto-restart algorithm (1, 5, 15 and 60 minutes).
▪️Manual restart option via button on the housing.
▪️Maintains constant pressure during continuous water usage.
▪️Reliable hydraulic protection thanks to the integrated check valve and water-hammer damper.
▪️Built-in pressure gauge for easy system monitoring.
▪️Can be installed directly on the pump or on the discharge pipeline.
▪️Adjustable pump start pressure: 1.5–2.5 bar.

The PRESSDRIVE 2E is an ideal solution for automating domestic water supply systems and long irrigation cycles, offering stable pressure and reliable equipment protection.
