The third generation of JTEKT HPI micro power packs is based on a 100% modular design which incorporates exclusive elements :

An exclusive JTEKT HPI motor 
A die cast support which is able to incorporate functions directly without requiring blocks 
A series 0 pump which allows to increase the service rate of the power pack 
The possibility of creating complex systems by fitting valves on a set of ports and a cavity for cartridge valve with integrated electronic control 
A wide range of tanks from 0,5 to 5 litres as standard

The choice of motors

JTEKT HPI micro power packs are available in direct current or in alternating single and three phase current :

Direct current: flow 0.75 to 8.6 l/min. at a maximum pressure of 280 bar.
JTEKT HPI has exclusive motors derived from motor vehicle technology which allows higher power to be obtained with improved service and minimum overall dimensions.

The JTEKT HPI 400 W motor is thus only 78 mm long, with a diameter of 100 mm.
 
Alternating current (single and three phase): flow from 0.75 to 6 l/min. at a maximum pressure of 280 bar.

Cartridge design concept

To ensure a bigger reliability and maximum adaptability, HPI power packs are designed around a system of cartridges which fit directly into the support.

The pressure relief valve and the check valve are two cartridges inserted into the support which is easy to disassemble for modification or maintenance. 
Poppet valves such as VNF, VNO, VLB, 4/2, 4/3 and even proportional valves can be fitted directly into the support without a block! 
VNF : Normally closed valve
VNO : Normally opened valve
VLB : Bi-directional logical valve

Adaptability

The design of the micro power pack 3G allows building of complete hydraulic systems incorporating :

Compact motors 
A support allowing the production of complex applications by integrating hydraulic functions into a set of ports and a cavity for cartridge valves. 
The possibility of assembling directly a simple or double effect jack on the support! 
Integration of electronic control of valves on the power pack 
A range of standard tanks which allows adaptation to the application with the smallest possible overall dimensions  

A full range of alternating or direct current motors 
     
Pump capacity of 0.25 to 2 cm3/rev. 
 
Tanks for all applications from 0.5 □ 6.3 liters
