SJ2-M hydraulic diaphragm metering pumpDetailed product description：

Main applications
High pressure and high flow conditions are required in petroleum, petrochemical/chemical processes, or for the injection and transportation of hazardous chemicals in onshore and offshore oil and gas dismantling systems. Key processes in industries such as nuclear power, military, environmental protection, pharmaceuticals, papermaking, and food can also operate safely without any medium in the pump head
Main features
Design and Manufacturing Standard GB/T7782-1996
It can remove residual gas in hydraulic oil to maintain its rigidity,
High measurement accuracy
Completely sealed without leakage
The diaphragm position control system is fully supported in the rear position
Main performance parameters
Maximum single head flow rate: 50000 liters/hour
Maximum discharge pressure: 50MPa
Steady state accuracy ± 1%
Medium viscosity: 0-800mm2/s
The temperature of the conveying medium can reach above 450oC
High performance diaphragm pump head
Standard stainless steel hydraulic end
Single head maximum flow rate of 50000 liters/hour, maximum pressure of 50MPa standard PVC hydraulic end
Single head maximum flow rate of 10000 liters/hour, maximum pressure of 10 bar
Built in combination safety valve to prevent overpressure and automatic exhaust
Measurement accuracy ± 1%
The temperature of the conveying medium is 150oC, and in special circumstances it can reach 350oC
PTFE diaphragm, easy to install without leakage
Adopting the latest technology, automatic control of oil replenishment, safe and reliable
Diaphragm pump (on-site/remote) rupture detection can use pressure or electrolyte type transmission end lubricating oil and hydraulic oil at the hydraulic end completely isolated, with low maintenance costs
