_Swashplate Axial Plunger Variable Pump for Closed Loop Hydrostatic Transmission

_Flow rate is proportional to driving pace and displacement and can be variable steplessly.

The circulation price boosts from zero to its maximum with the swashplate swing angle.

The liquid movement route can be transformed effortlessly by making the swashplate swing in excess of the middle.

Variable modes that are very easily matched with numerous management and regulation programs

The pump is outfitted with two relief valves at the high force oil aspect to safeguard the hydrostatic transmission (pump and motor) from overloading.

Large pressure relief valve also has the purpose of filling valve.

Constructed-in auxiliary pumps are utilised as refueling pumps and management pumps.

The greatest filling strain is constrained by a developed-in filling aid valve.

Entire series with created-in force shut-off valves


Security guidelines
– A4VG pump is made for use in closed circuit.
– The task plHangZhou, set up and commissioning of the axial piston unit need to be carried out by certified staff.
– Ahead of making use of the axial plunger device, remember to go through the corresponding manual totally. If essential, you can get it from Bosch CZPT.
– In the course of and shortly right after procedure, there may possibly be a chance of burning of the axial piston unit (specially the electromagnet). Proper security actions (these kinds of as wearing protective apparel) must be taken.
– The characteristics of the axial plunger device could differ with different functioning problems (doing work stress, oil temperature).
– Work pipeline oil outlet:
· Oil nozzles and set threads are designed for highest specified force. CZPT or program makers must ensure that the safety element of connecting components and pipes meets the specified functioning conditions (pressure, circulation, hydraulic oil, temperature).
· Work pipeline nozzles and practical nozzles are only employed in hydraulic pipelines.
– The info and recommendations contained listed here must be adopted.
– The product can not be authorized as a part that follows the standard mechanical protection concept of ISO 13849.
– The subsequent tightening torque is utilised:
· Connector:
Refer to manufacturer’s recommendations for tightening torque of the joints utilized.
· Put in bolts:
For installation bolts with ISO metric threads in accordance with DIN 13 CZPT and with ASME CZPT threads, we advise that the tightening torque of every single box be checked in accordance to VDI 2230.
· Thread holes in the axial plunger device:
The highest allowable tightening torque MG Max is the highest value for the inside threaded holes and shall not exceed that benefit.
· Locking screw:
For the metal locking screw offered with the axial piston unit, the fastening torque MV needed for the locking screw must be used.
