Japanese Sumitomo gear pump product description
Name: Gear pump
Model: Single internal gear pump Double internal gear pump
Brand: Sumitomo
Country of Origin: Japan
Description of Single Internal Gear Pump
Features
Ultra-low noise performance internal gear pump has smooth internal gear contacts and silent continuous rotation. Its outstanding feature is the special gear design, which makes the sound extremely low when in use. Even at high speed, the audio is still smooth and peaceful.
High operating wear resistance In addition to the simple mechanical structure, the use of high-grade hydraulic oil can reduce the wear of the mechanical surface and various functional parts. The pump can operate at high pressure and high speed, and even if ordinary hydraulic oil is used, it is not easy to wear parts.
The extremely low pressure pulsation pump can almost completely eliminate pressure waves, so it can be used as an ideal mechanical tool for precise speed control of the system. It can be used in a wide range of pressures
Precautions for use
Please use hydraulic oil with a viscosity grade of ~ Quite hydraulic oil. Anti-wear hydraulic oil with a viscosity grade equivalent to ~ is recommended for high pressures above /. Please consult our company when using flame-resistant hydraulic oil, water glycol, phosphate ester,/emulsion, etc. The hydraulic oil must be clean to prevent foreign matter or water from being mixed in. If the hydraulic oil changes color and stratifies, and white bubbles are mixed in, it means the working fluid It has deteriorated and the working fluid must be replaced.
Viscosity and oil temperature The recommended working viscosity is ~ / the working temperature is ~. Please use the suction pressure within the ~ + range, and above, please use high-pressure oil seals.
The oil filter installed on the suction side of the oil filter, the oil filter on the oil discharge side, and the use of magnetic oil filters can increase the service life.
Pump installation The base on which the pump is installed must have sufficient rigidity. The suction port of the pump is placed on the side to suck oil upward. The connection between the pump drive shaft and the motor shaft uses an elastic coupling or a chain coupling. If the eccentricity error is not present, the pump drive shaft cannot withstand any radial vertical force. Side drive methods such as belts, chain gears, etc. are prohibited. The coupling can be freely assembled on the pump drive shaft.
All oil pipes connected to the pump port are connected by flanges. The diameter of the suction side pipe should be within the flow rate, the negative pressure should not exceed the selection, and should be as short as possible.
Before starting the pump, add lubricating oil to the sliding surface and fill the inside of the pump body with working oil. When starting the pump, the pressure must be relieved and the air in the pump body and suction pipe must be discharged by starting and stopping repeatedly.
The definition of steering is always viewed from the shaft end, and standard steering is clockwise.
The definition of maximum pressure uses / which accounts for one cycle at the maximum pressure, and the continuous time is controlled within seconds.

Description
Power refers to the power required under the instantaneous highest working pressure condition.
When the operating speed is /, the driving power can be calculated according to the value / in the approximate formula table to obtain its approximate value.
Can be matched into a double pump.
