WES has a wide range of pump spares and system accessories for every application. Contact us today for more information and advice on the best solution.

Pumps, spares and
service kits

WES offer a full range of spares, accessories and service kits to support all chemical pumps and packages supplied.

Chemical tanks and bunds

WES can offer from stock 50l to 500l standard PE chemical tanks with 110% bunds. Alternative materials and higher capacities available to order.

CDS100 controller

The CDS100 controller is for dosing systems where there is a requirement to switchover between dosing systems manually or automatically.

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.

Flow verification

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

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.

Gauge guards

Gauge guards are designed to enhance the performance of chemical feed systems, by maintaining optimal pressures and protecting against chemical attacks.

Injection quills and fittings

Injection valves allow for passage of liquids from a freed line into the centre of a process line. The integral check valve feature does not allow process fluid to enter or travel back to the injection line, which is beneficial in keeping liquids separate at the mating interface.

Pulsation dampers

Pulsation dampeners are an effective solution for pulsation, vibration and noise reduction in fluid piping systems.

Suction foot valves/strainers

Foot valve / strainers are designed to improve chemical feed pump performance & reliability. WES offer a broad selection to suit your application, including options with integral float switches to warn of chemical exhaustion.

Dosing hose and adaptors

WES can support a full range of chemical resistant metering hose for both pump suction and discharge applications, including dual contained needs.
