vfd hydraulic pump made in china

Kawasaki Precision Machinery (Suzhou) Ltd. was founded in Suzhou, Jiangsu, China in 2005 to manufacture and supply Kawasaki hydraulic components such as hydraulic pumps and motors in China. In 2015, the company started producing robots in addition to hydraulic products. This is Kawasaki’s second manufacturing facility for industrial robots after the first in Akashi, Japan.

The Bear retrofitting of existing pumping stations means substantial energy savings, mainly when operating under partial loads, can be achieved. It can be efficiently transformed into any standard asynchronous pump motor suitable for variable speed drive operation.

The modular design of Bear makes it fundamentally different from ordinary variable speed pump drives. You can efficiently configure almost any pump arrangement according to your needs. It can up to six pumps be combined.

The cost saving is not only reflected in the energy-saving, which saves the customer’s use cost! The pump operation and monitoring protection logic is built into the Bear’s inverter so that it does not require additional relays or contactors; PLC can realize the function of controlling and protecting the water pump and motor; the operation is simple; no professional electrical engineer is required.

A hydraulic power unit (HPU) is a common product that IFP supplies to its customers for all types of hydraulic applications.  Most customers order their HPUs with standard electric motors and across-the-line motor starters.  These electric motors spin at a constant RPM.  Because the electric motor spins at a constant RPM, the hydraulic pump coupled to the motor is constantly flowing oil and is likely wasting energy in between system operations.

By allowing the VFD controlled HPU to match the system pressure and flow requirements by varying the pump speed, there are several other advantages to using these VFD controlled HPU systems.  By reducing energy put into the system, less heat is generated that has to be dissipated by the system.  There are typically noise reductions with VFD controlled HPUs.  With reduced heat and reduced system shock, this typically leads to longer component life depending on the load cycle.  Hi-lo systems can now be completed with just one fixed displacement hydraulic pump.  By over-speeding the pump for extra volumes of fluid, the VFD controlled system does not need a low pressure/high flow pump along with the high pressure/low flow pump.  Charging an accumulator can become more efficient as well.  Once the accumulator is charged, the VFD controlled HPU can slow down the flow output of the hydraulic pump and maintain the system.  Unloading the pump for accumulator charging is typically done with extra valves and consuming unnecessary energy.  Overall costs of hydraulic systems can be reduced because smaller hydraulic pumps can be used, less valves are required, less or no cooling for heat dissipation, and smaller reservoirs can be used.

The applications are endless for VFD controlled HPU systems.  These systems can be used on anything from a simple filter and lubrication system to extremely complex test stands and presses.  With increased efficiency and control, VFD controlled HPU systems will become more common in industry.

The Advanced Automation Workholding Pump includes a state-of-the art control interface. It begins at the Human Machine Interface (HMI) which allows easy access to store programs on Vektek’s Pump Controller. This interface displays the status of the on-demand pump, valve functions, pressure switch status, and any possible faults. The unit also comes with spare Input/Output allowing additional sensors to be plugged in, gaining the options of monitoring other critical fixture status such as pneumatic part presence sensing.
