High speed metering pump is suitable for injection pump with medium and low pressure, small and medium flow, high viscosity of conveying medium, and certain metering requirements. The structural feature is that the power and liquid transmission gear of the original machine are in different pump cavities, and the flow passage part adopts high-strength corrosion-resistant alloy and metal graphite double end face mechanical seal for long-term continuous operation, which has higher reliability. It is mainly used for the measurement and transportation of corrosive liquid or the liquid with high requirements for sanitary grade. The flow passage parts are austenitic stainless steel 304, 304L, 316, 316L and alloy stainless steel. After strict solid melting treatment, the material lattice and chemical composition are uniform, and the intergranular stress is small.
High precision ensures accurate flow, no pulsation and repeatability. The design is unique, the motor and the metering pump adopt the kneading drive connection, which eliminates the influence of the alignment error between the motor and the metering pump on the measurement accuracy, and also prevents the motor from transmitting the vibration to the metering pump.
