V4 Submersible Pumps Design
Single or multistage centrifugal pumps in pump shroud or in ring
section design. Radial or mixed flow hydraulic systems; Suction casing
fitted between motor and pump. A suction casing is fitted between the
pump & motor. Suction casing is fitted with strainer to protect the
pump from coarse particles / sand in the fluid. Pumps with check valve
(non-return valve) in option are supplied. Available with threaded
particularly suitable for vertical installation in narrow deep wells.
Additional bearings are fitted depending on the number of stages.
Stainless Steel inserts are fitted to the impeller. The impeller hub is
protected by stainless Steel inserts are fitted depending on the number
of stages. Stainless steel inserts are fitted to the impeller. The
impeller hub is protected by stainless steel inserts. This design
improves the starting torque & has the effect that solid particles
such as sand are propelled outside.

Salient Features Of V4 Submersible Pumps
Premier
manufacturing technology. The innovative mechanical design, combined
with the use of an advanced manufacturing technology, results in a
state-of-the-art 3-inch submersible pump line.
Proven & Reliable Design For Critical Conditions.
State of the art design: Delivers optimum performance and reliability in the toughest conditions.
25,
40, 50,100,150,165,170 & 200 LPM models feature independent
centrifugal impellers to provide smooth starting and long life.
Thick
(2.0MM) stainless steel outer casing shell to protect and align
internal submersible pumps components. Rigid connection between motor
and pump provides a single, perfectly aligned unit.
Rubber & bronze bearing provide low friction and high wear resistance.
Easy
assembling, dismantling. Easily serviceable pump & field rewindable
motors. Suction screen and coupling are made of stainless steel.
Standard 2 pole speed motor (2900 RPM).
Once assembled, each 4” borehole submersible pump is individually tested to assure performance within design specifications.
Kiwi Pumps uses non-contaminating, water filled motor design.
High pumping efficiency for reduced running costs.
Cost
effective pumping systems: The hydraulic design is such as to enhance
the efficiency, thus reducing energy consumption and making pumping
systems more cost effective.
Light weight and compact.
Lip seal and sand guard to prevent ingress of impurities into the motor.
Maintenance and service: with time some parts subject to wear may need replacement.
The
simplicity of the assembly concept allows for easy field service
without the need of special tools minimizing the system down-time.
The
MOTOR is of non-toxic cooling bath type; asynchronous with squirrel
cage rotor. Suction and delivery casing are in cast iron and if
required in stainless steel & brass. Impellers and diffusers are in
Noryl homologated for drinkable water use and are equipped with
stainless steel inserts in correspondence of the wearable zones.
Discharge Bearing: Extra long sealed top bronze bearing insures shaft alignment and stabilization for extended life.
Suction
Adapter: Designed to ensure proper pump/ motor alignment. Open area
permits easy access to pump/motor coupling. Casting made of ductile
iron for increased strength.
Pump
Shaft: High tensile type 410 stainless steel provides strength and
corrosion resistance. Ground and polished for smooth bearing surface.
Bearings
with sand channels; all bearings are water lubricated and have a
squared shape enabling sand particles, if any, to leave the pump
together with the pumped liquid.
The motor adapter, coupling, check value and discharge head may be removed without disassembling the hydraulic stack.
