ASPIRA 50

Pump in stainless steel for suction up to 2mm, 2 poles, 0.37kW,
Max head: 7 m,
Max capacity: 150 L/min

Description

Small pump in stainless steel AISI 304 with the suction positioned on the bottom of the pump. This model permits to suck the water up to 2 millimeters from the ground. Moreover, contrarily to other similar pumps, ASPIRA 50 is able to suck water even if the initial level of the water is only a few centimeters. The pump is supplied with a float-switch and it can be used as a standard pump (working with the float-switch) or blocking the float-switch in "ON" position in the apposite connection when the pump must suck water up to 2 millimeters. Thanks to these characteristics this model is ideal to drain the water from flats floor after floods when there is no pit to collect water. The pump is supplied with a hose connection including a no-return valve.

ATTENTION: As the suction is on the bottom, the performance gets reduced when the pump lays on the ground and cannot be kept lift up
