Progressing Cavity Pumps HE series

hopper pumps with trolley for food and winery sectors

Series with hopper an auger feed screw to convey directly the product to hydraulic part, are the ideal machines for pumping viscous and non-flowing, with a very high solids content.
Version with large eccentric rectangular hopper, auger feed screw, and integrated trolley. Ideal for enological sector in connection with the destemmer, for pumping the crushed grapes or without stalks. Extremely compact construction realized in stainless steel AISI 304 as standard, in all its components.
It is used a worm helical bevel gearbox to optimize the available space. As standard is supplied with welded mesh protection on the hopper, carter for motorization protection and e large handle suitable to implement electrical panel and inverter. Can be supplied with level probe into the hopper for automatic switching off of the pump.

Variants

DHE Series

The motorization is integrated into the machine construction. Angle gearboxes of the worm type are used, this allows to have a remarkable axial compactness, following the dimensions of the eccentric hopper. The reducer is coupled by a male shaft at the pump inlet. The protective housing installed on the hopper protects the motor preventing its deterioration.
