JTM hydraulic diaphragm metering pump

Configuration

• Adjustment methods are versatile, supporting manual, variable-frequency, and automatic remote control.
• a) Standard configuration: pump head made of 304 stainless steel, standard motor rated at 380V, 50Hz.
• b) Optional configurations: pump head made of 316L stainless steel, pump head made of 304 stainless steel with F46 lining, Hastelloy alloy pump head, titanium pump head, variable-frequency motor, explosion-proof motor, motor rated at 440V or 220V.

Features

• 1. No dynamic seals, easy maintenance, low noise, and convenient operation.
• 2. The motor is mounted vertically, ensuring safety and leak‑free performance.
• 3. Available with various types of insulated pump heads (including steam‑heated, hot‑water‑heated, and electrically heated options).
• 4. The inlet and outlet are equipped with high‑precision check valve assemblies, effectively guaranteeing metering accuracy and smooth flow.
• 5. Capable of handling highly flammable, explosive, highly toxic, malodorous, and strongly corrosive media.
• 6. Metering accuracy surpasses that of mechanical diaphragm pumps, while sealing performance exceeds that of plunger pumps.
• 7. Incorporates an advanced three‑valve system—overload protection, limit switch, and oil‑refill control—which ensures adequate hydraulic pressure in the hydraulic chamber, prevents over‑refilling, and eliminates hydraulic shock. This balances the forces acting on both sides of the diaphragm, extending diaphragm life by more than 8,000 hours.
