Dongkai quality Safety Relief Valve for Back Pressure 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

Dongkai is a leading China Ammonia dosing pumps manufacturers. Ammonia dosing pumps, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

The small solenoid diaphragm Acid Liquid Chemical Metering Dosing Pump offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.

Dongkai is a leading China Chemical Dosing Pump for Ammonia manufacturers. Chemical Dosing Pump for Ammonia's working Principle: The motor drives worm gear pair; through eccentric mechanism, rotary motion of the motor is transformed into reciprocation of slide bar. Reciprocating slide bar directly propels mechanical diaphragm to make cyclic deformation, so as to suck in and discharge the medium....

China Hot Sale Aluminum Air-Operated Diaphragm Pump Factory. Aluminium Alloy Air Operated Diaphragm Pump is a novel volumetric pump that uses compressed air as the power source to distribute air through the reciprocating motion of the air valve and drives the diaphragm to squeeze the conveying medium.

The Phosphate dosing pump is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator or control drive. The integrated controller allows the pump to adapt quickly and reliably to changing metering tasks.
