At the dosing pump

The miscellaneous accessories include sensors, water metres, back-pressure valves and vent valves, which allow continuous dosing on the suction or pressure side.

Valve AssembliesValve Assemblies

For a perfect dosing result

Valve assemblies are suitably premounted fittings consisting of a diaphragm shutoff valve and spring-loaded relief valve.

Double Diaphragm SystemDouble Diaphragm System

For a perfect dosing result

The standard version of diaphragm dosing pumps integrates a separating chamber function. For increased requirements, a second separating chamber can be added. Thus a better protection of the pump gear unit is ensured. In the case of a diaphragm failure due to wear, a contact between the medium and the atmosphere cannot be excluded. As a result, the environment might be endangered or molested inadmissibly.

Pressure Loading and Relief ValvesPressure Loading and Relief Valves

Keeps the operating pressure of the pump constant

Pressure loading and relief ralves are fittings for dosing plants. They are used, according to the user's requirements, to increase dosing accuracy or to protect the plant against excess pressure. Where the supply pressure is higher than the dosing pressure, dosing is not possible without a pressure loading valve.

Contact Head Water MetersContact Head Water Meters

For a perfect dosing result

Even when there are large flow fluctuations ideal proportional dosing is achieved by contact head water meters emitting pulses in proportion to the flow rate. The water meters are multijet wet-operating types with summarizing dosing works.

Diaphragm Isolating Valves

For a perfect dosing result

The isolating valves are derived from the pressure loading and relief valves. The result is reduced inventory for a whole series of spare parts, and greater flexibility in service. The isolating device is a flat diaphragm which is pressed over the hand-wheel, the spindle and the diaphragm disc on the seat. These valves are completely leak-proof.

Calibration ColumnsCalibration Columns

For a perfect dosing result

JESCO’s Calibration Columns are an important addition to any chemical feed system. They help ensure that the pump is pumping the specified amount of fluid by providing verification of the flow rate of the metering pump, thus they are instrumental in accurately metering the process fluid.
