2.1 General description
The 989 v2 range of lubrication pumps are particularly suited for plants with 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 grease distributed, the type of grease or the
type of distribution.
This construction technique is based essentially on the following modules:

Electric motor;

Pump body;

Pumping element;

Reservoir.
The bearing structure is the same for any version. The pumping element constitutes the essential
module.
Two types of reservoirs with different volume (from 5 or 10 kg÷11 or 22 lbs) can be arranged on
the pump body with stirring paddle and electric level indicator.
The 989 v2 OEM is fully protected against the external environment and can operate without
difficulty even in the most severe environmental conditions.
