IRG / Clean-water circulation range

IRG Single-Suction Centrifugal Pump

IRG is a single-suction centrifugal pump range for clean-water service. Its catalogue spans multiple discharge sizes and motor speeds and describes vertical and horizontal installation designs. Cast-iron casing construction and model-specific impeller options make it a separate choice from the CDLF multistage family.

Series overview

Overview

The IRG catalogue describes a broad single-suction centrifugal series for domestic, civil and industrial clean-water applications. It gives performance tables, model codes and construction information, including a cast-iron casing with protective coating and impeller materials that vary by configuration. The range includes both vertical and horizontal designs.

The appropriate layout, motor version and hydraulic duty should be selected from the relevant model data; the series name alone does not define a common connection or impeller material. IRG suits circulation and transfer where the liquid is compatible with the documented construction. The documented application is clean-water circulation and transfer.

Features

  • Single-suction centrifugal hydraulics
  • Vertical and horizontal designs in the catalogue
  • Cast-iron casing with protective coating
  • Model-specific impeller material options

Applications

  • Clean-water circulation
  • Civil water transfer
  • Industrial water systems

Materials

Cast-iron pump casing and connection, SS304/cast-iron impeller, SS304/45# steel shaft and SiC/carbon/SS304 mechanical seal as listed; confirm the selected construction.

Operating conditions

Clean-water applications are listed. Single-phase supply is shown up to 3 kW; three-phase supply is also listed. Check the series catalogue for the selected configuration.

Before selecting

  • Match required flow and head to the selected two-pole or four-pole hydraulic data.
  • Confirm liquid compatibility with the chosen impeller, shaft and seal materials.
  • Check installation arrangement, connection size and available electrical supply for the exact model.

Series questions

Is every IRG impeller stainless steel?

The material table lists SS304/cast iron. Confirm the impeller material of the selected configuration.

What does the four-pole suffix indicate?

The model code identifies the -4 suffix as a four-pole motor. Use its corresponding performance data when selecting the duty point.
