Open impeller submersible pump TECNO

Description

TECNO is a submersible electric pump for clear or slightly dirty water with open multi-vane fully submerged impeller.

The particular strength of TECNO submersible electric pump, obtained without sacrificing their easy-to handle qualities, make them suitable for use in domestic/civil drainage jobs and for medium-heavy duty professional uses.

Best uses on construction sites and for dewatering floated areas, for civil and industrial waste water, emptying out sump pits, water recirculation in painting or cooling plants.

Motor asynchronous squirrel cage type in dielectric anti-oxide oil bath, protection degree IP 68 and insulation class F.
Motor housing Cast iron GG 25, shaft stainless steel AISI 420, electric cable neoprene H07RN8-F oil resistant, bolt A2 class AISI 304, O.ring and lip seal nitrile, mechanical seal on silicon carbide + allumina.

Features

TECNO series

TECNO series pump is equipped with vertical horizontal output.

On request, these pumps can be supplied with duct-foot pedestal for automatic coupling.

Permanent submersible version with automatic coupling foot code 1″1/2 or 2” depending on pump model.

TOP TECNO series

TECNO series pump is equipped with vertical vertical output.

The special construction ensures long life, with limited and easy maintenance also the outlet vertical, encourages its use in wells of limited size.

The submersible pump TOP TECNO is also available with magnetic float switch.
The magnetic float allows the pump to work in small wells where the electromechanical float does not have the space to do its work. Used with dirty water by providing a regular cleaning.

magnetic float switch is not available for TOP TECNO 7-8-10-11 version.

Submersible pump TECNO and TECNO TOP are available in M version (1 ~ 230 Volts Single-phase), MG version (1 ~ 230 Volts Single-phase with float switch or T version (3 ~ 400 Volts = Three-phase).

TECNO 1-2-3-4-5-6

Single-phase feeding with incorporated motor protector and with built in capacitor and the three-phase feeding with compulsory protection to be provided by the user.

TECNO 7-8-10-11

Single-phase feeding: 1,5 HP with incorporated motor protector and with built in capacitor; 2 HP with box control.
The three-phase feeding with compulsory protection to be provided by the user.

The submersible pump TECNO 8 MG and 11 MG is available with starting capacitor and motor protector in the external box control.

The submersible pump TECNO have an open multi-vane fully submerged impeller with free passage from 12 up to 22 mm depending on model size.
