Moog Speed Controlled Pump System

Moog has released a pump system designed to provide injection-moulding and blow-moulding machine builders with a motion control solution that can lower energy consumption in hydraulic machines by up to 30%. The Moog Speed Controlled Pump System is based on three of Moog’s products - a fixed displacement radial piston pump (RKP), a brushless servomotor and a modular multi-axis programmable motion control servo drive (MSD).

The primary advantage of the Speed Controlled Pump System is the energy savings produced by the variable speed pump design that are not typically available with the traditional hydraulic technology used in injection-moulding and blow-moulding machines. In a normal hydraulic application, the machine experiences partial, medium and full loads as part of the cycles. In tests conducted by Moog with customers, the efficiency of the SCP with a medium load has reached 20-30% higher when compared to the conventional system. If a machine is running without load, or in a standby mode, energy consumption can be 90% less.

The system is compact, enabling the overall footprint of the machine to be reduced. Moog’s system, with its modular, integrated design, can be easily integrated into machines. It is also quieter for operating personnel with acoustic emissions up to 9 dB(A).

The design of the system is flexible to meet unique customer requirements. If required, the pump can feature a dual displacement pump design, capable of intelligently switching from one to the other displacement.
