AKA.AKAC (Motor Driven Grease Pumps)

This motor driven grease pump is used in single line centralized lubricating systems. This automatic lubricating system has been designed to be simple and streamlined, and uses a single-piston pump mechanism which is driven by a geared motor.
• Motor Capacity Reduced By Improved Efficiency
Use of a geared motor drive has improved efficiency, and this has reduced motor output to one half of that of previous models (in-house comparison).
• Simple Pump Mechanism
As a result of a non-spring check valve and single-piston pump mechanism, the pump mechanism is kept simple and is almost fault-free.
• Low-cost Automatic Lubrication
The pump and control panel are integrated, which enables easy automatic lubrication. Also, even more substantial automatic lubrication is possible if this pump is operated with a separately installed standard electric control panel.

• The set pressures of the safety valve are 23 MPa for grease and 13 MPa for oil, respectively.
• As this is an indoor type pump, protection such as installing the pump inside a cubicle is required, for example, when it is to be used outdoors or in poor environmental conditions.
• Select NLGI consistency #0 to #1 for centralized lubrication for the grease used. (Note, however, the grease used shall be unworked with the consistency of 240 or more at the operating temperature.)
• Foundation bolts are not included.

Explanation of Model Symbols

Note) Attachment of electric control panel
• The EK-3(T) control panel is attached only on the AKAC-108 type.
• Only a low level switch can be connected and controlled on the 3(T) type control panel.
• Note that the high level switch cannot be connected. When performing high level switch control, consult with us.
• Items marked by an asterisk * are applicable to only the AKA-104 and 108 types.
