HORIZONTAL MULTISTAGE PUMPS
A horizontal multistage centrifugal pump consists of two or more impellers. They are used in pumping services of moderate-to-high TDHs (total dynamic head). Each stage is essentially a separate pump.
All the stages are within the same housing and installed on the same shaft. Eight or more stages can be installed on a single horizontal shaft. Each stage increases the head by approximately the same amount. Multistage pumps can be either single or double suction on the first impeller.
All Pumps have been supplying and servicing horizontal multistage centrifugal pumps, such as Javelin Pumps, for over 40 years.
AVELIN HORIZONTAL MULTISTAGE CENTRIFUGAL PUMPS
The JH and JHI series are non-self-priming, horizontal multistage centrifugal pumps. The pump is closely coupled to the motor and mounted on a base plate.
These pumps are built to AS/NZS 4020 Standard and are safe for drinking water.
This user-friendly design makes the pump suitable for installation in small domestic and industrial water supply or transfer applications. The pump is fitted with a mechanical seal and a common pump motor shaft.
OVERVIEW
PERFORMANCE RANGE 50HZ
PUMPS
The JH and JHI series are non-self-priming, horizontal multistage centrifugal pumps. The Pump is closely coupled to an electric motor with a common shaft and mounted on a base plate. This design makes the pump suitable for installation in small domestic or industrial water supply systems. The pump is fitted with a mechanical seal and a common pump motor shaft.
JH – The discharge and suction chamber are made of cast iron. The other parts of the pump in contact with the liquid are made of stainless steel.
JHI – All parts of the pump in contact with the liquid being pumped are made of stainless steel. EPDM or Viton elastomers are available as standard.
APPLICATIONS
- Domestic
- Liquid Transfer and circulation
- Pressure Boosting
OPERATING CONDITIONS
MOTOR
The pump is fitted with a totally enclosed, fan-cooled motor.
OPERATING CONDITIONS
- Liquid: Clean liquid without solid particles.
- Liquid temperature range: 0 C ~ +90 C.
- Maximum ambient temperature: +50 C.
The maximum operating pressure depends on the temperature of the pumped liquid.
