Description
DIVER electric pumps are utilised for lifting clear water
from boreholes, first water collection tanks or cisterns,
wells or water courses and are capable of distributing
pressurised water to domestic installations, small
agricultural plants, and sprinkler systems for lawns and
gardens.
The pump, which is very silent running, can be installed
inside boreholes and sumps and eliminates all potential
problems of suction and unpriming.
Multi-stage close-coupled borehole pump with hydraulic
section below motor, which is cooled by the pumped
liquid. Impellers and diffusers in fibreglass-reinforced
Noryl with wear-resistant stainless steel thrust ring. Outer
liner, stator sleeve, upper head with delivery connection
and closing ring in AISI 304 stainless steel.
Supports in brass. Rotor shaft extension in AISI 304
stainless steel.
Lip seal on motor side and silicon carbide/silicon carbide
mechanical seal on pump side.
Submersible asynchronous two-pole motor made entirely
of stainless steel, featuring dry design with external
cooling by pumped liquid.
Canned AISI 304L stator. Squirrel cage rotor running on
ball bearings, oversized to ensure low noise, reliability
and durability.
On request, CONTROL BOX for the single-phase version.
Protection for the three-phase version is the responsibility
of the user.
Automatic version available with float switch. -
