Types of Dosing Pumps

Mechanical dosing pump
Mechanical dosing pumps are commonly used in dosing pumps and are a common type of dosing pump. Mechanical diaphragm pumps move diaphragms back and forth by mechanical actuation for fluid intake and discharge. They are also subject to different levels of wear than piston pumps , mechanical diaphragms are also subject to pulse discharges and other effects. However, this can be mitigated by having two diaphragm settings. Another advantage of mechanical dosing is that their construction makes them hermetically sealed, making them the best choice for toxic fluids.

Hydraulic dosing pump
A hydraulic dosing pump is a dosing pump that uses hydraulic power to drive the dosing mechanism. It controls the flow of dosing liquid by utilizing hydraulic pressure to move a diaphragm or plunger. Hydraulic dosing pumps are widely used in a variety of industries and applications where precise dosing of chemicals or additives is required. One of the advantages of hydraulic dosing pumps is that they can handle a wide range of flow rates and pressures, making them flexible for a variety of dosing needs.

Solenoid dosing pump
Solenoid dosing pumps are a special type of dosing pumps that use solenoid valves to control the flow of liquids for precise metering and dosing by means of an electromagnetically driven piston or diaphragm. It can be widely used in industry, water treatment, medical and laboratory fields. It is often used where high precision and stable flow control is required, and can be used in automated systems for precise dosing according to a predetermined program.

Packing And Transportation

When it comes to packaging, we always adhere to the principle of "safety first, details paramount." We meticulously design and customize packaging solutions for different pump models based on their size, weight, exterior structure, and quantity. Durable wooden boxes or high-strength cartons are typically used for exterior protection, while high-density foam, sponge, or shock-absorbing materials are filled inside to create a comprehensive cushioning layer, effectively reducing the risk of vibration, impact, and crushing during transportation.

For pumps with precision components or specialized structures, we also implement additional support and protection measures, such as customized linings, fixed slots, or partitioned isolation, to ensure the equipment remains stable and secure during long-distance transportation, multiple handling, and complex climates.

This scientific and rational packaging approach not only minimizes transportation losses but also ensures that every pump reaches our customers intact and in optimal condition. This demonstrates our commitment to product quality and customer experience.

FAQ

Q: What is a metering pump?

A: Metering pump, also known as dosing pump, quantitative pump or proportional pump, as the name implies metering pump is a kind of machinery can measure the delivery of liquid, it is a kind of can meet all kinds of strict process needs, the flow can be in the range of 0-* stepless adjustment, used to transport liquid a special volume pump. Metering pump according to the flow part can be divided into plunger, piston, mechanical diaphragm, hydraulic diaphragm type; According to the driving mode can be divided into: motor drive, electromagnetic drive; According to the working mode: reciprocating, rotary, gear type.

Q: How does a metering pump work?

A: Metering pump is mainly composed of three parts: power drive (motor), fluid transport (transmission frame parts) and adjustment control (pump head parts). The power drive device drives the fluid conveying diaphragm to achieve reciprocating movement through the mechanical linkage system: the diaphragm (piston) will be transported in the first half of the stroke of the fluid suction and in the second half of the fluid discharge pump head; Therefore, fluid throughput can be controlled by changing the reciprocating movement frequency or the stroke length of each reciprocating movement. The precise machining accuracy ensures the precise measurement of the conveying medium at each pump.

Q: What are the types of dosing pump?

A: 4 conventional metering pump types are designed for different pressures, chemicals and applications. They vary by pumping action and mechanism：

Q: Diaphragm (constant injection) pumps use diaphragms, pistons and valves at the inlet and outlet to fill and empty their chambers.

A: Diaphragm (pulse jet) pumps also use a diaphragm mechanism, but instead of a constant flow rate, a solenoid coil draws in the chemical and injects it in pulses.
Lobe pump A pump that allows a certain volume of fluid to pass through a meshed gear impeller.
Peristaltic pumps are very accurate in metering. The flexible bent tube allows the fluid to pass through and the flow rate is controlled by a roller, which is moved by an external robotic arm.

Q: Which pump is commonly used for metering pump?

A: In many industries and applications, the use frequency of electromagnetic diaphragm metering pump and mechanical diaphragm metering pump will be relatively high, small flow generally with the former, large flow will use the latter.

Q: What is a diaphragm metering pump?

A: Diaphragm metering pump due to the use of hydraulic oil evenly drive diaphragm, overcome the mechanical direct drive pump diaphragm force is too concentrated disadvantage, improve the diaphragm life and working pressure upper limit.

Q: Where to buy metering pump?

A: You can tell us what you need by submitting the form on the website, and then we have special personnel to connect with you and confirm the technical parameters, delivery and logistics information, we support the trade of the vast majority of countries in the world.

Q: Where is the dosing metering pump used?

A: Suitable for high pressure, low pressure, strong (weak) corrosion and high measurement accuracy.
For example, additives used in the petroleum industry and natural gas extraction; Chemical industry used for adding proportional chemical media; For environmental protection on the industrial water treatment pump; Dosing pump for purifying water treatment in boiler of thermal power plant, etc
