Showa Lubrication System
Depending upon the required lubrication system, a compatible pump and distribution equipment must be selected to enable correct operation to take place. Lubrication system chart
Lubrication System Selection
Mixing pumps and distribution equipment from different types of systems may cause faults.
By referring to the chart below, an appropriate lubrication system and components for a specific requirement can be identified.SHOWA Lubrication System Chart
Distribution Equipment / Applicable Pump Units
Distribution Equipment Description Application Pump Units
Measures exact amounts of oil to be distributed, which is not affected by pressure or viscosity.
The Dester plunger will discharge its pre-measured volume of oil by utilizing the direct pressure produced by the pump.
Pumps will need to possess a pressure displacement mechanism, enabling the Dester plungers to replenish itself with oil.Motorized

Measures exact amounts of oil to be distributed, which is not affected by pressure or viscosity.
The Dester Block will discharge its pre-measured volume of oil by utilizing the pressure produced by the internal spring.
The DSBs are suited for lower pressure systems, as discharge is induced by a spring and not by the pump’s discharge pressure.LCB3 TMS Model

The DG piston distributors, will discharge a pre-measured amount of grease, utilizing the pump’s discharge pressure.
Pumps will require a pressure displacement mechanism to enable the DG to replenish itself with grease.
To be used in conjunction with GD distribution blocks to simplify installation.Motorized

The Flow Proper Unit (Meter Unit) will apply flow resistance according to the number displayed on the unit.
Oil from the pump unit can be distributed proportionally by applying various levels of resistance at lubrication points.
The unit is best suited with accumulative pressure type pumps (no pressure displacement mechanisms).Motorized

Dester Valve distribution junctions possess adjustable flow-rate valves on each port, allowing simple flow adjustments to be performed.
No replacement or additional parts are required for basic adjustments and modifications in lubrication output, making system design, installation and modifications simple to perform.
VA & VB units are suited for both the intermittent and continuous type resistance systems and can be used in Total Loss or Circulating lubrication systems.
