Product Description
380V 0.18KW 0.5-20 L/H Hot Sale Cheap PVDF Diaphragm Metering Pumps From China
Working Principle
The motor drives the worm gear pair and converts the rotational motion of the motor into reciprocating motion of the sliding rod through an eccentric mechanism. The reciprocating motion of the sliding rod directly drives the mechanical diaphragm to undergo periodic deformation, achieving the suction and discharge of the medium.

Feature
★ Advanced single and double diaphragm design, with a multi-layer diaphragm structure that has been rolled to ensure uniform stress and durabilty of the diaphragm;
★ The PTFE material double diaphragm has excellent corrosion resistance and penetration resistance.
★ The diaphragm status monitoring system can output signals when the diaphragm is damaged, and can continue to work until the diaphragm is replaced or the pump is stopped diretly, without polluting the measuring medium;
★ Accurate eccentic structure design, with cam and spring eccentric mechanism and integral sleeve adjustable eccentric transmission mechanism.
★ The static seal of the hydraulic end diaphragm replaces the dynamic seal of the plunger, so it can achieve zero leakage of the conveying medium;
★ The sliding rod directly drives the diaphragm to move instead of using hydraulic pressure to drive the diaphragm for reciprocating periodic motion, making the structure of the mechanical diaphragm pump simpler and easier to maintain;
★ Patented mechanical diaphragm design ensures stable flow output;
★ Whether it is during shutdown or operation, smooth and stable output flow can be continuously adjusted by adjusting the knob;
★ There is no safety relief device, it is recommended to install a safety valve on the outlet pipeline of the pump.
Application:
Diaphragm metering pumps are widely used in various fields, including petrochemical, pharmaceutical, catering, thermal power plants, nuclear power, environmental protection, mining, national defense and other scientific research and production departments.
Diaphragm metering pumps, especially mechanical diaphragm metering pumps, mainly exist in the form of compound metering pumps in the past, which can be divided into various types such as single cylinder, double cylinder, three cylinder, etc. according to the number of cylinders. This type of pump has a very wide range of applications, covering almost every field from petrochemicals to environmental technology. Specifically, the application areas of diaphragm metering pumps include but are not limited to:
In the field of petrochemicals, diaphragm metering pumps play an important role in industries such as petroleum, chemical, textile, food, papermaking, atomic energy technology, power plants, plastics, pharmaceuticals, etc. They are used to accurately and quantitatively transport liquids without solid particles into pressurized or atmospheric pressure vessels and pipelines.
In the pharmaceutical and food industry, diaphragm metering pumps are used to precisely control the delivery of liquids, ensuring product quality and safety.
In the fields of environmental protection and energy, diaphragm metering pumps are used in thermal power plants, nuclear power, environmental protection, mining and other departments to handle various liquid media, playing a key role in environmental protection and energy production.
Defense research: In the defense research and production sector, diaphragm metering pumps are favored for their precise control and reliable performance.
