Pressure relief valves
Pressure relief valves are designed to protect chemical feed systems from over pressure damage caused by defective equipment or a blockage in the chemical feed line. They are available in ‘M’ Series – 1/4″, 3/8″ and 1/2″ and ‘G’ Series 1/2″, 3/4″, 1″, 11/2″.
Pressure loading valves
Apply positive discharge pressure to a metering pump system to prevent siphoning and aid accuracy.
Back pressure valves are used to stabilise the downstream pressure from a pump and ensure consistent flow.
Available as an accessory for your chemical metering system, ranging from a simple visual flow verification unit to a sophisticated chemical flow validation and transmission / feedback system.
Flow verification sensors are a great diagnostic tool for chemical feed pumps. They are designed to monitor pump output, with the pumps electronics continuously monitoring micro-flo to ensure chemical injection.
Calibration vessels are used to verify and calibrate the output from a diaphragm or peristaltic dosing pump. This then enhances the performance of the chemical feed system, by providing a verification of the flow rate of the chemical feed pump.
They help improve accuracy, efficiency, longevity, and safety. Available in PVC or glass.
Injection quills and fittings
Suction foot valves/strainers
Foot valve strainers are designed to improve chemical fed pump performance, preventing debris from entering the pump and therefore clogging the check valves or interior. Foot valve / strainer (with check valve) is recommended for diaphragm pumps (Chem-Feed). Foot strainer (no valve) is recommended for peristaltic pumps (FlexFlo).
The capacity of the strainers is 300 microns and available in isolation or as part of an installation kit.
