Areas of usage:

The different combinations of materials allow their use for varied applications, providing a broad
hydraulic coverage and proven efficiency.

They are particularly suitable for pumping clean liquids with low impurity content, low
viscosity, corrosive, hot, acidic, or alkaline.

  • Sugar and alcohol;
  • Water distribution in general;
  • Food and beverages;
  • Paper and cellulose;
  • Chemical, petrochemical, and pharmaceutical industries;
  • Textile industries;
  • Irrigation;
  • Fire-fighting installations;
  • Air conditioning;
  • Civil construction, etc.

Constructive Characteristics

Horizontal construction with closed single-stage impellers and extensively designed housing. Excellent wear resistance under the most severe working conditions. In the EQP version, the housing is provided with feet cast into its body for attachment to the metal base.
Suction flange is horizontal, and discharge is vertical upwards.

Oil bath lubrication and rotation to the right (clockwise) as seen from the drive.
Standard drive with electric motors.
Available in grey cast iron, nodular cast iron, stainless steels, special steels with specific heat treatments.


The flanges are made according to ANSI. They may be made using other standards.


The axle sealing is made through gasket or standard/special mechanical seal. When assembled with gaskets, the shaft is provided with a replaceable wear sleeve.

The mechanical seals may be single or double, internally or externally mounted, and according to the service conditions. The stuffing boxes may have lubrication systems that are externally sourced.


Made through flexible coupling with or without spacer.


Volute Spiral-type volute fixed to the bearing housing and mounted on its feet. In most models, the feet fixation is done at pump shaft height, what eliminates misalignments linked to the component’s thermal dilation.


The EQP-series pumps with closed impellers can be used in many industrial segments.

Shaft and Bearings

The shaft works with oil-lubricated ball bearings and its sealing is made with conventional gaskets or mechanical seal.
