JY25 Series Hydraulic Diaphragm Metering Pump
It is widely used in industries such as chemical engineering, petrochemicals, metallurgy, power generation, pharmaceuticals, food processing, plastic foaming, and industrial boilers. When conveying media at high pressure, high temperature, and high viscosity, it can be custom‑designed to meet specific customer requirements and configured with insulation, heating, or cooling features to satisfy application needs.
Characteristic
Application
- It is widely used in industries such as chemical processing, petrochemicals, metallurgy, power generation, pharmaceuticals, food processing, plastic foaming, and industrial boilers. When conveying media at high pressure, high temperature, and high viscosity, it can be custom‑designed to meet specific customer requirements and configured with insulation, heating, or cooling features to satisfy application needs.
Advantages
- Sealed with no leakage, hydraulically actuated diaphragm, maintenance-free.
- High-precision inlet and outlet check valve
- Equipped with a built-in adjustable pressure relief safety valve and an automatic oil‑refilling limit valve, it ensures metering accuracy.
- Dual diaphragm with rupture‑alert function (optional).
- PTFE diaphragm, service life ≥ 10,000 hours; metal diaphragm > 3,000 hours.
- Manual/automatic/digital inverter‑controlled flow regulation.
- Maximum suction head: 4.2 m water column
- Medium temperature: PTFE diaphragm ≤ 120°C, metal diaphragm ≤ 200°C
- A variety of pump head materials are available: PVC, PTFE, PVDF, 304SS, 316SS, Alloy 20#, Hastelloy C, and others. Maximum applicable fluid viscosity: <2000 cP.
