ZYB Series High Pressure Gear Oil Transfer Pump for Waste Oil
ZYB series residual oil pump adopts self-sealing lubrication, the gap automatically adjusts the structure, and the parts are made of high wear-resistant materials. It has the characteristics of compact structure, good self-priming, high efficiency and strong adaptability. When the liquid is contaminated, the working life of the pump is more than 10 times longer than that of the general gear pump.
The design of the residual oil pump fully considers the interchangeability with the KCB series of ordinary gear pumps. The shape and installation dimensions and technical parameters are the same as those of the KCB series gear pumps. Therefore, this type of pump is also called "strong" type of KCB series. It also shows the important characteristics of long life and stable pressure of the pump when conveying medium with lubrication and no impurities.
This type of ZYB residual oil pump is suitable for transporting impurities such as heavy oil, diesel oil, coal tar and grain, oil, chemical, building materials and daily chemical products with a temperature not higher than 200 ° C and a viscosity of not more than 150 mm 2 /S containing non-metallic impurities. A variety of media with less lubrication.
The ZYB residual oil pump is especially suitable for applications requiring stable working pressure and long-term continuous operation. For example: strong lubrication system, fuel delivery and injection in fuel burning systems, etc.
ZYB residual oil pump is not suitable for transporting corrosive, metal-containing impurities, sandstone impurities with a particle diameter greater than 3mm, and high volatility.
A medium with a low flash point. Such as: gasoline, benzene, etc.

| Discharging oil or discharging little oil | 1.Revolving direction reversed 2.Valve closed 3.Oil absorption tube has not been soaked into the oil 4.The high of absorption exceeds the rated 5.The filtering area of the filter at absorption end is too small 6.Air leakage in absorption tube 7.Safety valve blocked or doesn’t work well 8. Lower temperature of oil results in viscosity increasing | 1.Change in to right direction 2.Open valve 3.Check out oil absorption tube and soak it in the liquid 4.Measure absorption pressure and raise the oil level 5.Change filter and extend the filtering area6.Check every joint and seal them with sealing material 7.Disassemble and wash safety valve and polish with abrasive grease 8. Heat liquid or reduce exhausting pressure or the volume of oil exhaustion |
| No pressure or pressure not rising | 1.The button of the pressure meter is still in OFF position 2.The pressure of the safety valve is too low3.Side tube valve is on 4.High temperature,low viscosity o foil and small resistance of the tube 5.Air leakage in the tube | 1.Press the button ON of the pressure meter2.Readjust the safety valve pressure 3.Close the side tube valve 4.Reduce oil temperature 5. Check out absorption tube |
| Oil leakage in mechanical seal | 1.Shaft seal has not been adjusted properly 2.O-seal ring wear 3.The defects caused by wearing of stationary and rotating rings of mechanical seal4.Spring flabby | 1.Adjust it 2.Change O-seal 3.Change stationary and rotating rings or polish the magain4.Change spring |
| Noise and vibration | 1.Improper assembling 2.The in concentricity of pump shaft and motor shaft 3.Absorption tube or filter stopped up 4.Absorption tube dimension is too small and long.It could not pump in,for resistance is too big 5.Oil exhaustion tube’s resistance is too big6.Air leakage 7.Fastener is relaxed 8.Gears and bearings stand sides show serious wear and tear or gripped | 1.Check out and maintain 2.adjust it 3.Clear dirt things in the absorption tube or filter 4.Read just it 5.Check up whether exhaustion tube or valve are stopped up6.Check up and maintain7.Check up and tighten it 8.Disassemble and maintain or change them |
| Safely valve unworkable | 1.Wrong position2.Pressure too high 3.Safety valve chip gripped | 1.Reassembling it2.Lower the pressure 3.Disassembling,wash and adjust |
