3. Machine description
The MINISUMO II range of lubrication pumps are particularly suited for dual-line and progressive systems and can adapt to
many needs without mechanical modifications, even after installation. In fact, be choosing a set of components that are
perfectly compatible with one another and easy to assemble, you can vary the pressure, the quantity of lubricant
distributed, the type of lubricant or the type of distribution.
This construction technique is based essentially on the following modules:
Motor
Pump body
Two pumping elements
Reservoir
Valves and output assemblies (inverter, pressure adjustment valve, etc.).
The bearing structure is the same for any version. The dual pumping element constitutes the essential module.
The pumping element normally has only one outlet, but the version with separate outlets can be requested.
Two types of grease and oil reservoirs with different volumes (10 or 30 kg~22 or 66 lbs) can be arranged on the pump
body with stirring paddle and electric level indicator.
The MINISUMO II electric pump is fully protected against the external environment and can operate without difficulty
even in the most severe environmental conditions.
3.1 Intended use and prohibited use
3.1.1 Intended use
The MINISUMO II pump is the ideal electric DropsA pump for use with single and dual line systems.
Lubrication systems engineered with the Dual Line System are generally used on large scale machinery and in harsh
operating conditions to lubricate multiple points on large machines.
NOTE: The pump is designed to work with maximum NLGI 2 grade lubricants.
Use NBR gasket compatible lubricants.
Any residual lubricant inside that was used for assembly and testing is NLGI 2 grease.
A table is shown that compares the NLGI (National Lubricating Grease
Institute) and ASTM (American Society for Testing and Materials)
categories for greases, limitedly to the values that involve the pump.
For further information on the technical characteristics and the safety
measures to adopt, see the Product Safety Data Sheet (Directive
93/112/EEC) related to the type of lubricant selected and supplied by
the manufacturer.
