Diesel Engine

DESCRIPTION

Fire Driver® diesel engines are specifically designed for fire pump applications. The proven technologies used throughout the design and manufacturing ensures the reliable operation of these engines during fire condition.

Air-Cooled Engines
These air-cooled direct injection diesel engines are smaller in volume, lighter in weight and lower in fuel consumption. The improved cooling and combustion properties results in the highly efficient performance of this engine. FD-AR series comprises of single cylinder 4 stroke air cooled diesel engines.

Radiator-Cooled Engines
FD-RW series comprises of 3, 4, 8, 6 & 12 cylinder 4 stroke compression ignition type engines. These engines have improved performance and combustion efficiency. The characteristics such as high torque and heavy duty construction makes these engines a right choice for fire fighting applications.

These engines are subjected to rigorous performance tests prior to the dispatch to ensure that the performance ratings are achieved as required by the design specifications.

Horizontal Split Case Pump

DESCRIPTION

  • Standardized design with reliable performance
  • The cast iron casing is axially split which permits removal of the complete rotor without moving either piping or motor. Pumps generating high heads have double volutes to reduce radial forces, ensuring minimal shaft deflection and low bearing loads.
  • The bronze closed type impellers have double curved vanes. The double suction design gives practically zero axial forces. Each impeller is statically and dynamically balanced.
  • The carbon steel shaft is fully sealed against the liquid being pumped. Shaft protecting sleeves are fitted in the seal area.
  • Replaceable cast iron rings protect the casing at the impeller running clearances.
  • Stuffing box is fitted with mechanical seal. Pump can be supplied with gland packing also.
  • Bearings are grease lubricated deep groove ball type.

End Suction Pump

DESCRIPTION

  • Fully complies with both performance and dimensional requirements of DIN 24255.
  • The cast iron volute casing is of robust design with integrally cast feet, vertical top centerline discharge with axial suction incorporating cast inlet vane to give best flow to impeller eye.
  • The bronze double shrouded type impeller is hydraulically balanced and positively driven by shaft key and axially locked between sleeve and impeller nut.
  • The stainless steel shaft is fitted with a domed type locking nut.
  • Replaceable wearing rings are fitted as standard to all casings and also to back covers on larger pumps which reduces maintenance time and cost.
  • Stuffing box is fitted with Mechanical seal. Pump can be supplied with gland packing also.
  • Bearings are ball type grease lubricated and sealed for life.
