Lubrication System Selection

Depending upon the required lubrication system, a compatible pump and distribution equipment must be selected to enable correct operation to take place.
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.

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	MLA*W, MLB*W Models	Intermittent Type + Pressure Displacement
			LCA3 Model
			LCA4 Model
			LCB3 Model
	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

			LCB5 Model
		Pneumatic	HP*W* Model (Contact Showa)

	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	GPMW30 Model
		Manual	GPHW01 Model
	Measures exact amounts of lubricant to be distributed, which is not affected by pressure or viscosity. The Dester G will discharge measured volumes of grease through each port, one after the other in sequence (progressively). Blocks with differing discharge volumes selectable. A visual indicator pin or a limit switch option is available.	Motorized	MHG4 Model	Continuous Type + Progressive discharge
			MHG7 Model
			GPM101 Model
	Measures exact amounts of lubricant to be distributed, which is not affected by pressure or viscosity. The Dester G will discharge measured volumes of grease through each port, one after the other in sequence (progressively). PSG attachments can be attached to combine ports. A Visual indicator pin or a limit switch option is available.		GPM102 Model
		Manual	SHG Model
			GPH Model
	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	YMAS Model	Intermittent Accumulative Pressure Type
			SMD Model
			SSMA Model
			MY6 Model
			MV Model	Continuous
		Manual	LD Model	Intermittent Accumulative
			EA & HLA7 Models
	The Continuous Unit applies flow resistance according to the number displayed on the unit. By applying various levels of resistance at junctions or lubrication points, the lubricant can be distributed proportionally. Unlike the PSS range, these units possess no internal check valves.	Motorized	MLA, MLC, MLD Models	Continuous Type
			MHG4, MHG7 Models
			GPM101, GPM102 Models
		Manual	SHG Model
			GPH Model
	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.
