ABT Series Servo Pump

ABT Series Servo Pump is high performance servo hydraulic system special oil pump. It is researched and developed together by three party- Ningbo Vicks Hydraulic Co., Ltd. American Albert Fluid Power Co., Ltd. Zhejiang University Mechanical Control Engineering Research Institute. The core components are imported from America. We have the proprietary intellectual property hydraulic systems of rubber and plastic machines, shoes machines, forging and press machines, bending machines and shearing machines.

Main Features

1.Dowel pin type vane kits designation can make the pump with small resistance, low electric, and with more energy saving.

2.se outside leakage and leakage volume control designation low the oil temperature obviously. Based on the hydraulic components leakage volume, can adjust the oil leakage smartly, the pump pressure pulse is small at high pressure and low speed, the injection finished products will be more higher accuracy.

3.With the coordination of high pressure oil and vice spring structure, can make the pump run normally at low speed, can fit low and high speed shift, high and low pressure speed shift, right and left rotation shift etc working status of servo hydraulic system perfectly.

4. Double action and right-left rotation structure designation make the pump work more steadily, servo hydraulic system response more quickly.

5. High pressure, high speed structure and double cutting edges designation make the speed range more wide, and with more better pollution resistance, more longer working life.

6. Low noise structure designation and wide range of flow, can be customized according to different requirements.

7. Use the cartridge kit installation structure, repairing only need change the cartridge kit, more convenient for repairing and with more lower cost.

8. Double pump use one inlet port and two outlet ports, the structure is more compact with small installation space.

9. There are four directions each at inlet and outlet port, installation is more flexible.

Note Oil pump structure design the world’s first, In China and world many countries have applied for a patent, Copy must strictly prosecuted.

Note: Details please read ABT servo pump Instructions. 

Leaked oil port 

1.Pump housing design with Rc3/8 leaked oil port, the leaking oil must through the port back to oilbox, do not blocking, or will cause the shaft seal damage.

2.Following photos instruction, Leakage of oil pipeline must be upward arrangement, make the sliding bearing in the pump shaft center in the leaked oil dip full lubrication.

3.Rc1/8 screw plug, inside is high pressure oil chamber, not removable, or may cause safety accident.

Installation, Application and Maintenance

1.Operating oil

● Anti-wear hydraulic oil is recommended for better performance and longer life. Viscosity range: 10-860cst, Recommended viscosity 46cst.

● Proper fluid condition is essential for long and satisficatory life of hydraulic components and systems. The filtration rating should not be lower than 25μm. Filter of 70-150μm on the inlet port is recommended and its rated flow should not be lower than 200% of pump’s.

Oil temperature range of pump working: 0℃-70℃. The best oil temperature is 10℃-60℃ for ensuring long-term and reliable life.

2. Installation

● Foot and frame for pump must be reliable, solid and good in vibration absorbent.

● Horizontal mounting is recommended to maintain necessary case fluid level. Concentricity of shafts between pump and motor is important to pump life and should be within ∅0.1mm. It is better to use flexible coupling to avoid harmful effects.

● Try to avoid using the steel pipe connection for tubing, the rubber hose is recommended for avoiding additional load causes the extra noise.

● The oil pump allows the inhalation vacuum as 110mm column of mercury. Installation should near fuel tank, inhaling the height can not be big in 500mm.

● Please notice the seal of flange at port connections, ports and absorb pipeline has to be sealed strictly, to prevent air leakage. If not it will cause the noise and vibration of system, also will make foam, to low the life of pump.

● The diameter of absorb pipeline should not smaller than that of inlet.  

● There should be a plank in the tank to separate bubble and dirty thing from used oil. Return pipeline under oil is recommended ( not connect with inlet) for avoid bubble.

3. Start

● Before starting pump, please check up if the inlet and outlet have been correctly connected and the rotation of the pump is inline with the nameplate. (CW without notice).

● After confirming it is able to work well without burthen, please restart.

● When initially starting the pump after long-time unused, removing all trapped air from the system can be accomplished by loosening flange or connections.

4. Maintain

● Please inject defend-rust oil in the pump, plaint the surface with defend-rust grease and then cover ports, if you do not want to use it right now.

● Please check up oil periodically, while if the oil can not reach the demand, replace it and clean up tank.

● Purging of filter regular is recommended.

● Keep the normal level of oil in the tank. When capability of tubing and tank are large, even if injected enough oil. Because when starting, the level of oil would fall, then please add some oil. Please observe the level of oil and add some oil when needed.

● After a period of working, it is likely that the install bolt and flange of inlet and outlet would loose because of vibrating. please tight them.

● The cartridge design of ABT series servo pumps offers fast and efficient field service ability, when replacing the cartridge, seals inside the pump should be checked to avoid them crimping, when tighting the fastening screws, they should be treated with even force in diagonal direction.
