Material Construction

Engineered for Dependability

Fire protection allows no second chances. Every UNIPUMP package is heavy-duty throughout — built for the long, low-run-hour, high-reliability life a fire pump has to deliver, and configured to NFPA standards.

10-Point
Construction Detail
Primary Platform

Horizontal End Suction

Heavy-duty construction throughout, with a back pull-out design that keeps the pump serviceable without disturbing the pipework. Key elements of the UNIPUMP end-suction platform:

  • 01

    Casing & Wear Rings

    Self-venting, radially split casing with replaceable case wear rings to sustain efficiency over the service life.

  • 02

    Enclosed Impeller

    Keyed, dynamically balanced impeller finished to absorb shock loads and deliver smooth, quiet flow.

  • 03

    Mechanical Seal

    Single or double mechanical seal to application — leak-free performance and reduced maintenance. Soft packing optional.

  • 04

    Bearings & Shaft

    High-strength ground shaft on cartridge-mounted bearings, protected by lip seals for a liberal safety factor.

Horizontal split-case fire pump for high-flow duty
High-Flow
Split Case
Also Available

Horizontal Split Case

Double-suction, axially split casing for high-flow fire-protection duty. The upper casing half lifts clear for inspection of the complete rotating element without disturbing suction or discharge piping — keeping heavy-flow systems serviceable with minimal downtime.

  • 01

    Double-Suction Impeller

    Balanced axial thrust and lower NPSH required for stable performance at high flow.

  • 02

    Axially Split Casing

    Top-half removal exposes the full rotor without breaking suction or discharge connections.

  • 03

    High-Flow Duty

    Suited to large commercial and industrial systems demanding elevated flow rates.

Design Features

Built for the Long Run

Every design choice targets reliability, easy maintenance and a long service life under demanding duty.

Back Pull-Out Design

Spacer coupling lets rotating elements be removed for service without disturbing suction or discharge piping — minimising downtime.

Hydraulically Balanced Impeller

Enclosed, dynamically balanced impeller assures smooth operation, reduced thrust and long bearing life across the duty range.

Heavy-Duty Casing

Centreline discharge, self-venting casing with replaceable wear rings and foot-supported design for optimum efficiency and rigidity.

Dual Drive Options

Choose electric-motor or diesel-engine drive on the same hydraulic platform — with a matched jockey pump to hold system pressure.

Stainless Shaft Sleeve

Stainless-steel shaft sleeve protects the shaft and reduces maintenance cost; mechanical seal or soft packing supplied on request.

Packaged & Tested

Delivered as a complete, factory-assembled skid with controller and accessories — installed, wired and ready to commission.
