2. GENERAL DESCRIPTION
The Sumo series of lubrication pumps may be adapted to many uses without making any mechanical changes even after it has
been installed. In fact, by making a selection from a set of components which are fully compatible and easy to assemble, the
pressure, quantity of lubricant delivered, actual type of lubricant or type of distribution can be altered.
This construction technique is essentially based on the following modules:
Electric motor
Pump body with integrated reducer
Two pumping elements
Reservoir
Valves and outlet unit (inverter, pressure adjustment valve, etc.).
There is only one bearing structure for all versions, with the dual pumping element constituting the essential module.
The pump unit possesses one single output, because the deliveries from the two pumping elements flow into a manifold unit.
Two types of tank for grease and two for oil with different volumes (of 30 or 100 kg) with stirring paddle and level indicators can
be arranged on the pump body.
The pump is controlled by normal electrical apparatus which is able to effect inversion and perform the programmed cycles.
The Sumo electric pump is fully protected against the external environment and can operate without difficulty under the most
severe environmental conditions.
