Metering pump installation, used for high pressure and ultra-high pressure cleaning pump, petrochemical, fertilizer process pump, copper liquid pump, oil field, salt mine injection pump, liquid carbon dioxide pump, pentasodium slurry pump, steel plant phosphorus and rust removal pump, etc. Assembly type: horizontal type, fixed type and mobile type. Drive mode: motor, diesel engine, gearbox, pulley, electromagnetic speed regulation, frequency control, etc.

Metering pump manufacturing, high pressure reciprocating pump, mainly used in petroleum, chemical, fertilizer and other industries as flow pump, oil field, salt mine as injection pump, steel pipe, pressure vessel as pressure test pump, booster pump, construction, shipbuilding, chemical and other industries as high pressure cleaner, boiler water supply, hydraulic machinery and food, medicine, instrument and other industries need high pressure fluid and process pulse requirements.

HVDC pump is composed of motor, coupling, reducer, transmission device, pump head, common base and other parts. The motor drives the crankshaft to rotate through the reducer, belt drive or stepless speed regulator, and drives the connecting rod to make the plunger move back and forth in a straight line through the slider (crosshead). Under the opening and closing action of the pump head inlet valve, the motor sends the liquid suction and discharge command. The pump head material of high pressure reciprocating pump can transport all kinds of high pressure liquid according to the needs of users.

It can use carbon steel alloy forging, stainless steel, inlet and outlet valve seat, valve sleeve, valve piece packing, plunger, etc. it is mainly suitable for petroleum, chemical, fertilizer and other industries as process pump, oil field, salt mine as oil injection pump, steel pipe, pressure vessel as pressure test pump, booster pump, construction, shipping, chemical and other industries as high-pressure cleaning and descaling, boiler water supply, hydraulic machinery drive source. And food, medicine, instrument and other industries have higher requirements for high-pressure fluid and process pulse. Gear pump is a kind of rotary pump which transports liquid or pressurizes by the change and movement of working volume between pump cylinder and meshing gear.

Two gears, pump body, front and back cover constitute two closed spaces. When the gear rotates, the space on the gear disengaged side gradually increases, forming a vacuum, sucking in the liquid, and the space on the gear meshed side gradually decreases, squeezing the liquid into the pipe. The suction chamber and the exhaust chamber are separated by the meshing lines of two gears. The size of the gear pump outlet pressure completely depends on the size of the pump outlet resistance.
