Vertical Multistage Jockey Pumps

DESCRIPTION

JVS / JVSS is a vertical multistage pump series with all wetted parts made of stainless steel. It is suitable for a variety different applications involving various liquids from potable water to industrial effluent.

Pump is rigidly coupled to a totally enclosed fan-cooled motor with Class F insulation and IP 55 enclosure rating, suitable for 50 Hz or 60 Hz power supply.

Its high head low capacity performance range makes it especially suitable for using as pressure maintenance pump (jockey pump) in fire fighting applications and it meets NFPA 20 requirements for jockey pumps.

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.
