Key Features of T7ES-E50 Series Vane Pump

Featured functions:

This type of vane pump is mainly designed for high/low-pressure hydraulic circuits, and the combination of different specifications of pump cores in double or triple pumps can meet the requirements of high pressure (up to 300 bar), small flow, and low pressure, as well as large flow conditions, which is a wise way to optimize the circuit design.
This type of vane pump can meet the requirements of a very rapid pressure change cycle, the output flow rate can maintain accurate repeatability, and has the following advantages:
● High working pressure: the maximum pressure of the small-size housing pump can reach 320 bar, which can reduce the installation cost, if the pressure is used, it can extend the working life; High volumetric efficiency: the typical value is higher than 94%, thus reducing heat, and under full pressure conditions, the allowable speed is as low as 600 rpm;
● High mechanical efficiency: the typical value is higher than 94%, reducing the power loss;
● Wide speed range (600 rpm ~ 3600 rpm): combined with the use of a large displacement pump core, small specifications can be used to form a large displacement of a low noise pump;
● Low speed (600 rpm), low pressure, and high viscosity (860 cSt) performance: allow to operate at low temperatures, with small energy consumption, and no risk of sticking.
Low-pressure pulsation (2bar): reduces pipeline noise and extends the service life of other components in the loop:
● Strong resistance to solid particle pollution: this is the effect of double-blade technology, long service life of the pump:) Installation and structure selection form (pump core displacement, transmission shaft type, and oil port configuration, etc.,) diverse: easy to use;
● The concept of pump core components: reduce maintenance costs exponentially;
● Note: Special design can be provided to optimize the noise characteristics of the pump.

Installation & Maintenance Guide for T7ES Pumps

To protect your rights, please read the following carefully

Pump Start-up Procedure 
Preparation Prior to Start-up 
The reservoir and circuit should be clean and free of dirt and debris prior to filling with fluid. 
Circuit Cleanup 
The reservoir should be charged with filtered hydraulic fluid. The fluid level should be sufficient to prevent vortexing at the suction connection to the pump inlet. It is good practice to clean the system by flushing and filtering, using an external slave pump. 
Filling Pump and Removing Air 
If the pump is mounted above the fluid level, it should be filled with fluid through the outlet port. If the pump is mounted below the fluid level, the pump outlet fitting (or other downstream fitting or plug) can be loosened to allow fluid to displace the air. It may be necessary to loosen the fill cap on the reservoir to allow the fluid to flow freely. When a solid stream of fluid with no observed air begins to drain through the loosened fitting, the fitting should be retightened. An air bleed valve in the outlet circuit is also recommended to remove trapped air. If such a device is used, the pump should be filled with fluid before start-up. In some cases, it may be possible to prime the pump by running the engine starter for five to ten seconds with the throttle and/or ignition switch in the "off" position. It will be necessary to loosen a fitting or plug in the pump outlet to allow air to escape. 
Pump Start-up 
All controls should be placed in the neutral position so the pump is unloaded when started. Start the engine and run at low idle. Once the pump is started, it should prime and pump within a few seconds. If it does not, make sure there are no restrictions between the reservoir and the inlet to the pump, and that there are no air leaks in the inlet line and connections.  Also, make sure that trapped air can escape from the outlet. Run at low engine idle for approximately five minutes. Then, while observing the reservoir fluid level, operate the implements. Extend all actuators to maximum safe limits to completely fill the system with fluid. Do not run with the fluid level below the "low" limit. Add fluid to the reservoir to bring the fluid to the proper fill level.
