Spare Part Kits includes all wearing parts, it can help users to shorten the equipment maintenance time and re-start up ASAP. If the repair kits are used to do preventive maintenance,a long-term stable operation can be ensured.

Back Pressure Valve can prevent siphon and build up back pressure between the outlet and inlet of metering pump to ensure the dosing accuracy. Normally the factory setting pressure is 2 bar.

Pressure Relief Valves can avoid damage of equipment or pipeline due to system over pressure. Once the valve is closed or pipeline is blocked, the system would be over pressure. Pressure relief vale will open when operating pressure is over vale setting pressure. Recommend to install pressure relief value.

 Calibration Columns is a system accessory installed with the reciprocating pump. It can reduce the impact from the pulsating flow to the pipeline system, and the influence of flow pulsation change to the chemical reaction. By installing pulsation dampeners in the outline pipe of a metering pump, the pulsating changes can be controlled within 5%.

Calibration Columns is used for flow calibration ofmetering pump, thus obtains with the flow/stroke relationship corresponding to the actual system and actual process fluid.The calibration column volume is no less than the 30 seconds rated flow of the metering pump.

Y- Strainer is installed on the metering pump inlet line.It is used for filtering process fluid to prevent impurities and particles into the metering pump, guaranteeing the accuracyof metering pump and keeping normal operation.
