Centrifugal Pump EQ

The EQ-series pumps (with closed impellers) have a broad field of application in the most diverse industrial segments.

They have components dimensioned to work in harsh conditions, allowing great sturdiness in the dimensioning of all their components.

Construction Features

The EQ-series centrifugal pumps are designed and built according to ANSI B-16.5 or B-16.1 150#.

Their execution is horizontal, single stage. The suction connection is axial horizontal, and the discharge is vertical.

The shaft works with oil lubricated ball bearings and the shaft sealing is normally done by conventional gaskets and/or mechanical seals.

According to the work conditions, wear sleeves with special coatings, lubrication, cooling, or internal/external sealing can be provided.

Hydraulic Characteristics

Impellers:Radial, closed
Pressure: up to 17.5 Kgf/sq cm (g)
Flow: up to 1800 m³/h
Temperature: up to 130°C

Spital-type volute, balance fixed to the bearing support. It has a vertical discharge flange, with the possibility of changing the position in 60° or 120° in relation to the center line in most models. 


Closed impellers can be used in a broad application field in diverse industrial segments.

Shaft and Bearings

The shaft works with oil-lubricated ball bearings and the shaft sealing is normally done with conventional gaskets or mechanical seal.
