plunger metering pump with crankshaft adjustment mechanism

Piston metering pump adopts high hardness ceramic piston or ceramic spraying piston, with excellent corrosion resistance, adapt to the harsh working environment, can be used in petroleum, chemical, metallurgical and other industries.

Description

Advantages of plunger metering pump:

  1. Ceramic plunger: The pump adopts high hardness ceramic plunger or ceramic spraying plunger, offering excellent corrosion resistance for harsh working conditions. Its smooth surface and high hardness deliver a service life over three times longer than traditional polished or electroplated plungers, suitable for long-term, high-load scenarios.
  2. High-quality packing seal: Uses PTFE base material packing seal components, featuring corrosion resistance, self-lubrication, and high-pressure load capacity. Combined with the standard ceramic plunger, this significantly improves pump service life, reduces maintenance frequency, and enhances overall economic efficiency.
  3. High load-bearing crankshaft adjustment mechanism: The pump features a high precision and stability stroke adjustment mechanism. Compared to traditional adjustment methods, the new crankshaft design delivers higher transmission efficiency, stronger load-bearing capacity, and more precise adjustment, ensuring long-term stable operation.
  4. Energy-saving and cost-effective: The parallel design of the main drive shaft and regulating mechanism increases transmission efficiency, reduces energy consumption, and extends service life. This cost-effective design greatly reduces maintenance and operating costs.

plunger metering pump Technical features:

  1. Flexible plunger size: Diameter from D6mm to D200mm, adapting to different flow requirements and supporting high-pressure applications.
  2. Wide flow rate adjustment: Freely adjustable from 10% to 100%, metering accuracy up to ±1%. Pressure range up to 50MPa.
  3. Flow regulation and control: Stroke length adjustment for accurate control. With frequency converter motor, supports motor frequency adjustment and remote control, as well as digital controller for on-site or remote monitoring.
  4. Custom features: Available with thermal insulation pump head (steam, hot water, electric heating), parallel configurations for conveying different liquids, flow rates, and pressures.
  5. Simple structure and cost-effective: Easy to maintain, highly cost-effective compared to similar products.
  6. Suitable for high-viscosity media: Handles high-viscosity media, not recommended for corrosive slurries or hazardous chemicals.
  7. Packing seal and maintenance: Packing seal assembly is core, with self-pressure locking and high-pressure capacity. Regular checking and adjustment of packing preload is required to maintain sealing.
  8. Safety protection: No built-in safety relief device; install a safety valve at the outlet pipe for safe operation.
