Product catalog summary

Overview: This document outlines the technical specifications for centrifugal pumps adhering to EN 733 standards, suitable for diverse applications such as shipbuilding, heating, air conditioning, and petrochemical industries.

Main Applications: These pumps are designed for use with fresh and sea water, condensate, oils, and chemical products. They are applicable in shipbuilding, heating plants, air conditioning systems, aqueducts, effluent treatment plants, fire fighting, and petrochemical plants.

Main Features:

Pump Type: Centrifugal, end-suction, single volute casing with axial inlet.
Impeller: High efficiency, closed type, balanced both statically and dynamically, with balancing holes to reduce axial thrust.
Mounting System: Shaft supported by radial and thrust bearings, available in oil bath or self-lubricated versions, with materials like cast iron, bronze, or stainless steel for special applications.
Seal: Single mechanical seal to DIN 24960, with options for special seals or cartridge types for specific applications. Soft-packing with external flushing is possible, and a cooling chamber can be fitted for temperatures above 120°C.
Self-Priming: Available for small and medium sizes with built-in priming elements, and all sizes can be supplied with an additional air ejector for self-priming.
Back Pull Out: Allows removal of rotating components without disturbing pipes, pump casing, and motor.
Base Plate: Typically made of welded steel, with options for stainless steel and anti-vibration features.

Special Versions: Pumps can be customized according to Naval Rules for shock-proof, vibration-proof, noise-proof, and non-magnetic requirements.

Materials and Pressure:

Materials: Cast iron, stainless steel, bronze, and special alloys.
Max Working Pressure: 10 bar for cast iron, 16 bar for stainless steel, bronze, and special alloys. Special executions exceeding these limits are available on request.

Interchangeability: Components such as models, casings, impellers, shafts, bearing brackets, covers, and mechanical seals are interchangeable across different models.

Dimensions and Specifications: Detailed dimensions and specifications for various pump types and sizes are provided, including flange dimensions, pump weight, and other critical measurements.
