Constructive Characteristics
Closed double-suction impeller. The axial forces acting are hydraulically self-equilibrated.
Opposite, horizontal suction and discharge flanges positioned on the lower body. Due to its design characteristics, it can be driven in clockwise or counterclockwise directions.
ANSI standard-executed flanges.
Driven by electric motor, internal combustion, or steam turbine. Flexible coupling with or without spacer.
Head: up to 190m
Temperature: up to 110°C
Revolution: up to 3500 rpm
Flanges: padrão ANSI
Housing
Split in the direction of the shaft line, provided with removable wear rings.
They have support feet as an integral part of the lower body, cast in one piece.
The lower body houses the bearing housings with two-supported bearings at the ends. It allows easy access to the rotating assembly, without having to disconnect the suction and discharge piping.
Impeller
Built with staggered blades.
In specific applications, such as mixing pumps (Fumpumps), it can be designed with anti-pulsating vanes.
Shaft and Bearings
Oil bath lubricated compact bearings, sized according to ISO 281 (ANSI / ABMA standard 9).
Shaft for continuous services, designed for maximum load with minimum deflection.
Wide range of applications
Rugged construction
Proven durability, reliability, and efficiency Simplicity of maintenance
Support network and service flexibility
Technical support throughout the product life cycle Performance and cost-effectiveness that make the difference.
Closed, double-suction radial impeller, statically and dynamically balanced. Resulting axial forces self-balanced hydraulically, reduced axial thrust.
Low NPSHr. Vibration-free stable operation.
2) Labyrinth Rings
Replaceable, design tolerances and clearances guaranteed.
3) Connection Flanges
ANSI standard execution.
4) Bearings
Compact, robust rigid ball-type. Grease lubrication.
Allows easy installation.
Long-life warranty.
5) Shaft
Designed for heavy duty and minimum deflection, fitted with removable wear bushings.
Executed in carbon steel, or other alloys compatible with the liquid.
6) Sealing System
Conventional gaskets or mechanical seals.
The lubrication of the gaskets can be made by the pumped liquid itself or by an external source.
