Horizontal split case fire pumps

Horizontal Split Case Fire Pumps are known for their robust and heavy-duty construction, coupled with superior design features that make these pumps highly reliable and efficient, while also requiring minimal maintenance. The fully enclosed double-suction impellers virtually eliminate axial thrust, and the bearings evenly distribute the radial load at each end of the shaft. This simple design allows for service without disturbing the piping at the site.

These pumps can be powered by either an electric motor (50Hz/60Hz) or a diesel engine, with a full range of options and accessories available to meet NFPA standard requirements. Heavy fabricated steel base plates mount both the pump and driver, along with a flexible coupling connecting the driver to the pump. Horizontal Split Case Fire Pumps are ideal for applications where the water source is above ground, providing a positive suction pressure throughout the pump’s performance range. These pumps are available for a wide range of applications and can be constructed from various materials to suit different needs.

CONSTRUCTION DETAILS:

  1. PUMP CASING: Rugged heavy-duty, volute type, compact casing split horizontally along the centerline of the shaft. Supporting feet integrally cast with flanged suction and discharge connections located in the lower half casing allows inspection and maintenance without disturbing piping.
  2. STUFFING BOX: Designed to accommodate a minimum of five packing rings with a lantern ring. Provided with internal passages to allow water for cooling and lubrication.
  3. IMPELLER: Double suction, fully enclosed, cast in one piece, dynamically balanced before the assembly. Impellers are firmly keyed and locked to the shaft.

HORIZONTAL SPLIT CASE FIRE PUMPS24. BEARING HOUSING: Rigid bearing housings provided with grease inlets and drains and protected by seals to keep contaminants out of bearings. Designed to allow the bearing to be replaced without disturbing any other part of the rotating assembly.

5. BEARING: Grease lubricated steel bearings to maintain the impeller in its central position. Bearings are selected to offer a very high operating life.

6. SHAFT SLEEVE: Centrifugally cast renewable stainless steel shaft sleeves that are accurately positioned, sealed, and locked in place protect the shaft against packing wear, corrosion, and leakage.

7. GLAND PACKING: Graphite packing rings are selected to offer maximum tightness while allowing smooth and friction-free running of the shaft.

8. LANTERN RING: Perforated hollow ring made of corrosion-resistant material designed to allow the flow of cooling water uniformly around the shaft to provide lubrication and cooling.

9. SHAFT: Made of high-strength alloy steel, accurately machined and polished to a smooth surface. Sized with a liberal safety factor to transmit full driver horsepower while offering minimum deflection in full-range operation.

10. CASING WEAR RING: Renewable casing wear ring sized to minimize pressure leakage from discharge toward suction
