installa-
tion. Mixed flow hydraulic systems with impellers that can be turned down. Pump
bearing lubricated by the fluid handled and protected against ingress of sand. Inte-
grated check valve with anti-blockage, spring-loaded valve disc / connection
branch. Pump end with internal thread / flange

. Suction casing with suction strainer
fitted between pump and motor.
Pre-filled submersible motor. Three-phase current. Squirrel-cage design with self-
aligning thrust bearing and adequately sized expansion diaphragm for pressure
equalization. Design in compliance with VDE standards. IP 68 enclosure. With power
supply cables. Required flow velocity past the motor: v ≥ 0.5 m/s.
Fluid handled: clean to slightly contaminated water, slightly aggressive / more
