Horizontal End suction fire pump

End Suction Fire Pumps are engineered to last long with a precision cast, dynamically balanced, and enclosed impeller that minimizes vibration and maximizes bearing life. Due to its back-pull-out design, the complete bearing assembly including impeller and casing cover can be dismantled without removing the volute casing from the pipe system. This innovative design simplifies maintenance and reduces downtime, ensuring the pump remains operational and efficient over its long service life.

These pumps can be driven by either an electric motor (50Hz / 60Hz) or a diesel engine, offering flexibility to suit various operational requirements. With a full range of options and accessories available, including controllers, jockey pumps, and relief valves, our End Suction Fire Pumps can be configured to meet NFPA compliance, providing reliable performance in fire protection systems. The heavy fabricated steel base is designed to mount both the pump and driver, with a flexible coupling connecting the driver to the pump, ensuring stability and efficient power transfer.

End Suction Fire Pumps are ideal when the water source is above ground, as they provide a positive suction pressure to the pump throughout the performance point. This ensures consistent and reliable water delivery, which is crucial for effective fire suppression. Horizontal End Suction Fire Pumps are available for a wide range of applications and are constructed from various materials to meet specific needs, including corrosion-resistant options for harsh environments.

At Fuller Electromechanical, we are committed to delivering top-tier fire pump solutions. Our End Suction Fire Pumps are built to stringent quality standards and are designed for durability, efficiency, and ease of maintenance. With our expertise in fire protection systems, we provide comprehensive support from selection and installation to ongoing maintenance, ensuring your fire pumps deliver optimal performance and reliability when it matters most.

Description

PUMP PERFORMANCE RANGE

  • Flow ranges from 50 GPM up to 1000 GPM
  • Pressure ratings from 80 psi up to 309 psi

REFERENCE STANDARDS

  • Underwriter Laboratories (UL) – 448
  • Factory Mutual (FM) – 1319
  • NFPA 20

CONSTRUCTION DETAILS:

  1. PUMP CASING: Rugged heavy duty, integrally cast supports, volute type, centerline discharge and self-venting. O-ring seals between pump casing and casing cover to avoid any leakage.
  2. CASING WEAR RING: Standard enclosed impellers are designed with integral renewable casing wear rings to reduce end thrust.
  3. IMPELLER: End suction type, enclosed, dynamically balanced prior to the assembly. Impellers designed with back rings to minimize axial thrust. Impellers are firmly keyed and locked to an accurately finished oversized shaft to absorb all shock loads.
  4. BEARING HOUSING: Heavy-duty cast bearing housing designed to accommodate bearings and supports the rotor assembly. Both the inboard and outboard bearings are protected by seals to keep contaminants out of bearing and provisions for filling grease.
  5. LANTERN RING: Perforated hollow ring made of corrosion resistant material designed to allow flow of cooling water uniformly around the shaft to provide lubrication and cooling.
  6. GLAND PACKING: Graphite packing rings selected to offer maximum tightness while allowing smooth and friction free running of the shaft.
  7. CASING COVER: Casing cover with integral stuffing box designed for maximum working pressure. Stuffing box sized to house five rings of packing along with lantern ring.

  1. SHAFT SLEEVE: Centrifugally cast renewable shaft sleeves protect the shaft from corrosion, packing wear and are sealed to prevent leakage. Sleeves are accurately positioned and locked in place.
  2. BEARING: Grease lubricated steel bearings are selected to carry loads while offering very high operating life.
  3. 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.
