Multistage Centrifugal Pump

Our Multistage Centrifugal Pumps are types of Industrial Water Pumps designed for various applications requiring high-pressure capabilities. This range, comprising the RN, TS and RAM models from Italian partner Salvatore Robuschi, excels in handling clean and dirty liquids. The RN and TS models feature Closed impellers, while the RAM model features a Regenerative Turbine impeller. RN models are suited to clean water without solids of up to 0.2% maximum, with the TS model better suited to clean and slightly dirty water. For applications requiring low capacity and high pressures, the RAM model is ideal. ATEX certification is available for this range, enhancing operational capabilities in hazardous environments.

Typical applications for our Multistage Centrifugal Pumps:

  • Industrial
  • Wastewater & Water Supply
  • Fire Fighting
  • Heating, Air Conditioning & Cooling
  • Circulation
  • Boiler Feeding
  • Irrigation
Overview

RN Series

The RN Industrial Water Pump series of Centrifugal Pumps are Single Stage End Suction Centrifugal Pumps fitted with Closed Impellers. These pumps are designed in accordance with EN 733 standards for nominal duty points and performances. This range of Centrifugal Pumps is suitable for clean water without abrasive solids (max allowable content of 0.2%), which are non-aggressive to the pump materials.

The pumps are ideally suited for industrial, water supply, fire-fighting, heating, air conditioning, cooling and circulation applications, and are often used within agricultural, civil and industrial markets.

This range features a Back Pull-Out design which enables quick and simple dismantling of the pump in the pipework.

The pumps are also available in ATEX executions.

TS Series

The TS series Multistage Centrifugal Pumps are ideal for use with clean or slightly dirty water.

This series is used predominantly in boiler feeding, fire-fighting, autoclave, water supply, washing plant and irrigation applications to pump hydrocarbons. They are also suited to applications that require high-pressure capabilities.

Cooling chambers are supplied as standard.

RAM Series

The RAM series is suitable for applications such as boiler feeding, washing plants and flotation plants in wastewater treatment and are ideal for use where low capacity and high pressures are required.

Features & Benefits
  • Built according to EN 733 norms
  • Enhanced modularity with 35 different pump sizes
  • 3 bearing housing and shaft groups available
  • For increased hydraulic efficiencies, Investment Cast Impellers are used (open impellers display similar efficiencies to closed impeller types)
  • Increased flexibility in operation owing to 2 impeller types that can be installed in the same casing. Additionally, 14 different sealing systems are available for fitting in the same casing cover
  • For greater application coverage, closed impellers are suited to clean fluids, while open impellers are better suited to handling non-abrasive solids, liquids with dissolved gases, and under demanding suction conditions
