High Flow Hydraulic Diaphragm Metering Pump JYDR
Capacity range 90-4900lph, 16-400bar
JYDR series hydraulic diaphragm pumps are rugged construction with dependable performance. The pump is designed with three automatic valves (internal relief valve, oil make-up valve, position limit valve), to keep the entire system hydraulically balanced for trouble-free dosing. The drive mechanism is full motion design, which can offer high pressure up to 400bars. The motor can be both vertical and horizontal installed. Multiplex gearbox with one motor drive and pump base is available.
Features of SHINJO Hydraulic Diaphragm Metering Pump:
Shinjo hydraulic diaphragm metering pump consists of three main devices: (1) driving device, (2) adjusting device, (3) liquid delivery device. The crankshaft which reduces motor rotation speed by worm and worm gear makes the piston reciprocate in the hydraulic oil chamber. This reciprocating movement of the piston makes the PTFE diaphragm and the liquid which is isolated by the diaphragm sucked and discharged. Each pump is with internal pressure relief valve protecting the pump from overpressure conditions.
The flow rate can be adjusted via unique adjusting mechanism from 0-100%. The adjustment can be carried when the pump is in operation or at stop. The steady state accuracy is ±1% from 30%-100% of the maximum output. Automatic operation is achieved by variable speed drive.
SHINJO hydraulic diaphragm metering pumps are capable of dosing corrosive, vaporing, flammable, explosive or toxic solutions. It can also transport suspended liquid or moderately viscous liquid.
Double diaphragm with diaphragm rupture detecting system is available to prevent the accident caused by the mixture of hydraulic oil and the liquid after diaphragm ruptures.
