Auto Flocculant Preparation for the liquid or powder polymer preparation, designed for homogeneity in flocculant concentration Optimized design to ensure the polymer goes through the maturation process using the smallest footprint Auto Flocculant Preparation is a compact unit that automatically feeds the process, as needed, using a regulated ultrasonic level switch.

Dongkai is a professional leader China Industrial piston pump manufacturers. A positive displacement pump in which the high-pressure seal reciprocates with the piston is called an industrial piston pump. Gases can be compressed and liquids moved using industrial piston pumps. They can function under a variety of pressure conditions. It is possible to operate at high pressure without significantly affecting flow rate. Solid particle and viscous media can also be handled by industrial piston pumps. This kind of pump works by means of a piston cup, oscillation mechanism, and filling of pump chambers through downstrokes that create pressure differentials and upstrokes that force the pump fluid out for use. Industrial piston pumps are frequently utilized in water delivery or irrigation systems and in situations where a high, steady pressure is required.

Find a huge selection of Positive Displacement Metering Pump from China at Dongkai. Positive Displacement Metering Pump's operating principle: Reciprocation of plunger drives hydraulic oil, and hydraulic oil drives the diaphragm to reciprocate, so as to suck in and discharge the medium.

Dongkai quality Safety Relief Valve back Pressure Valve help to relieve excess pressure on the pump system or maintain pressure at a setted point. Safely relief valve is installed on the outlet pipeline of metering pump. When the system pressure becomes abnormal, safety relief valve protects metering pump from any damages. Back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected. When dosing point is lower than the outlet of metering. Each Valve is diaphragm type with 2-port design, which can be used both as safety relief and back pressure valve

High precision and reliability Accurate Hydraulic Diaphragm Metering Pumps are highly precise and reliable metering pumps for chemical processes which achieve metering accuracy within ±1% (see Note 1), linearity within ±2% (see Note 3) and feature a driving unit specially designed for long-term continuous operation. Improved cost performance The mechanical efficiency of the reduction gear as well as that of the entire pump is improved. In addition, the employment of a large-capacity pump head and the standardization of high-speed types have further improved the cost efficiency of the pump. Compact and lightweight.
