Most hydraulic machines that have multiple functions that need to operate together at the same time will have more than 1, 2, or 3 Gear Pumps in Double or Triple Configurations (2 and 3 pumps in a row) for machinery and earth moving equipment with drive motors for wheels, tracks, and attachments as well as functions that use lift, tilt and or grab using cylinders.
We do have stock, you must call or message us with your required configuration for pricing.
Most hydraulic machines that have multiple functions that need to operate together at the same time will have more than one hydraulic pump bolted to the motor's bell housing.
Group 3 pumps max working pressure
up to 20cc = 300 Bar, 25cc-43cc = 250bar, 47-60cc =230bar
For example, Earth Moving machines such as dozers and loaders need to move wheels or tracks and at the same time operate cylinders to lift blades, tilt buckets and operate attachments such as grinders and trenchers.

2 or 3 pumps in a row are used because if only one large pump is used, oil flow will always take the path of least resistance back to the tank, using only one pump to one valve, will not give wheeled/track-driven machines good performance.
Therefore the best way to get different functions to work at the correct pressures simultaneously is to use two pumps & two valves or 3 pumps and 3 valves.
An alternative to Gear pumps is balanced Vane pumps, Balanced Vane pumps have a few advantages over gear pumps, generally have a longer life, smoother operation, are quieter, and are much more cost-effective to modify and or rebuild.
If you are not sure how many gear or vane pumps and valves you require and what horsepower you will need as well as what oil flows each pump needs to supply?
