Product information

Description

Omnigena HWA-18-M 1/4" male 230V is a pressure switch designed to control electrical supply to pumps based on measured system pressure. The device senses pressure changes in domestic and light industrial water systems and automatically starts or stops the pump to maintain preset pressure levels. Featuring a 1/4" male threaded connection and 230V electrical rating, this pressure switch is intended for inline installation on pressure lines or pump housings where automatic pressure control and pump protection are required.

Advantages

The pressure switch provides reliable automatic control of pump operation, reducing the need for manual intervention. Its compact construction and standard 1/4" male thread enable straightforward installation in common plumbing connections. Built to work with 230V single-phase power supplies, the unit helps protect pumps from dry-run conditions and prevents pressure fluctuations by activating the pump only when necessary.

Suitable for

  • Automatic start/stop control of domestic water pumps
  • Maintaining stable pressure in small pressure boosting systems
  • Protecting pumps from dry run in shallow well or tank-fed systems
  • Use in light industrial or agricultural water supply applications

Key specifications

  • Electrical supply voltage: 230V
  • Threaded connection: 1/4" male
  • Function: pressure-operated electrical switch for pump control
  • Typical installation: inline on pressure line or pump housing
  • Application environment: domestic and light industrial water systems

How to use

Install the pressure switch at a suitable point on the pressure line or directly on the pump discharge using the 1/4" male threaded connection, ensuring correct sealing and alignment. Connect electrical supply and pump wiring according to local electrical codes and the pump manufacturer's recommendations. Set the pressure thresholds and any available adjustment controls following the manufacturer's instructions so the switch activates the pump at the desired cut-in pressure and stops it at the cut-out pressure. Verify proper operation by cycling the pump and observing pressure response.

Usage recommendations

Before installation, isolate electrical power and depressurize the system. Use appropriate thread sealant compatible with potable water systems if required. Periodically inspect the switch and connections for leaks, corrosion, or wear and test the automatic operation to ensure continued protection against dry run and pressure instability.
