Tecnoidea’s submersible centrifugal pumps are designed to operate immersed in tanks or sumps. Designed for installation directly on the bottom of buried collection sumps, they integrate the pump hydraulic section and the electric motor in a single sealed unit. With pump bodies and key wear components protected by thick abrasion-resistant rubber, these machines are fitted with safety probes to detect any water ingress and to monitor overheating.
How the submersible abrasion-resistant pump works
Fully submersible configuration
Unlike the vertical or horizontal models, both the pump hydraulic section and the electric motor operate fully immersed in the fluid.
Motor and cooling
To operate in these conditions, the electric motor is sealed, insulated (insulation class F) and designed for continuous operation. The pump also incorporates an oil-cooling system.
Operational management
Pump control and automated level control inside the sump are managed by stainless steel rod probes (with the option of adding sonar or radar probes). The discharge connection is made using a double-flanged spiral rubber hose, to damp vibrations.
Safety and wear-resistant components
With the motor and hydraulic components fully immersed, dedicated sensors and wear-resistant materials are required to protect against water ingress and abrasion.
Safety sensors
To minimise the risk of water entering the motor, every pump is fitted with a safety probe to detect water ingress and a temperature probe to monitor motor overheating.
Cooling and seals
The system is further protected by a double mechanical seal and an oil-cooling system.
Thick linings
The pump bodies are lined with thick abrasion-resistant rubber, with either removable linings or rubber vulcanised directly onto the pump body.
Open impeller
The fluid is moved by an open impeller, which can be supplied rubber-lined or made of hardened high-chromium cast iron. The wear bush and shaft sleeve are also lined with abrasion-resistant rubber.
Vibration reduction
The discharge connection is made using a double-flanged spiral rubber hose, to damp vibrations.
