Our Solutions

Surge Tank

A Surge Tank is a surge control device, with pre-charge pressure calculated to deliver the required elasticity to push wastewater into the system following a pump trip, preventing hazardous pressure surges in the system.

Non-slam or Surge-arresting Air Valve

NR – Non-slam (NS) or Surge Arresting (SA) Air Valves are designed to both allow large air intake, preventing the risk of excessive negative pressure that may cause collapse of the pipe, and to restrict air outflow when discharge air velocity exceeds a threshold value. This creates a slow closing ‘air cushion’ that decelerates the […]
