plunger metering pump with motor driven worm gear pair

The working principle of piston metering pump is to drive the worm gear by the motor, and then drive the connecting rod through the adjustable eccentric mechanism to make the piston reciprocating motion. The volume chamber of the hydraulic end changes with the reciprocating movement of the plunger, and the check valves at the inlet and outlet open and close alternately to ensure the precise suction and discharge of the medium.

plunger metering pump Technical parameters:

• Maximum flow rate of single head: 1620 L/H
• Pressure range: up to 50 MPa
• Standard configuration: 304 or 316 stainless steel, 380V, 50Hz power supply configuration
• Optional configuration: 316L, 904, 2205, TA, Hastelloy C and other special materials, motor frequency / explosion-proof, special voltage / frequency options

plunger metering pump Performance characteristics:

1. High applicability and high precision: Plunger-driven hydraulic end, adapts to wide flow and pressure requirements, especially suitable for high metering accuracy. Plunger diameter ranges from φ6 to 200 mm for flexible selection. Simple design, easy to maintain, good efficiency for long-term use.
2. Reliable sealing performance: Equipped with high-precision inlet and outlet check valves for strong sealing and high pressure resistance. Valve group made of high quality, corrosion-resistant materials for long life.
3. Wearing parts and regular maintenance: Plunger and packing shaft seal are wearing parts, need regular check/adjustment of packing preload. Regular maintenance reduces leakage risks.
4. Customized features: Can be customized for special working conditions, such as high/low temperature, high viscosity, high solid content, special media. Temperature control ensures pump performance.
5. Parallel use and proportional pump function: Multiple heads for higher flow, reduced pulse, or proportional pumping of different media. Increased adaptability and flexibility for complex applications.
6. Automation control: Equipped with stroke controller for adjustable working status and automation. Useful for automated production lines, reducing labor costs and improving efficiency.

plunger metering pump advantages:

1. Precision and stability: Integral adjustable eccentric mechanism, infinitely adjustable stroke (0-100%), stability and linear accuracy up to ±1%.
2. Durability and long life: Full ceramic or sprayed ceramic plunger, high hardness, corrosion resistance, excellent finish for longer life, especially in harsh media.
3. Low maintenance costs: Packing seal design with ceramic plunger for superior self-sealing, less maintenance, lower costs, better for high pressure, temperature, and corrosive media.
4. Variety of valve group options: Multiple high-precision check valves (ball, stacked, angle types), valve seat usable both sides for lower cost and easier maintenance.
5. Customized temperature control: Hydraulic end can be customized for heating, cooling, or insulation to expand temperature adaptability.

plunger metering pump Application:

Plunger type metering pump is widely used in many industries due to its high precision, high pressure, high durability and good sealing performance. It is capable of handling a variety of high-pressure, high and low-temperature, high-viscosity and high solid-containing media, and therefore has a wide range of applications in the chemical, oil and gas, electric power, pharmaceutical, metallurgical, paper-making and other industries.
