Hidrostal Pumps

Municipal wastewater pumps with flexible configuration for treatment plants and pump stations.

Engineered to Keep Flow Moving

Hidrostal pumps are designed for demanding duties in treatment plants, pump stations and sludge handling. Their original screw centrifugal impeller helps move solids-laden flow more reliably – reducing the risk of blockages in jobs where conventional pumps can struggle.

Hidrostal Screw Centrifugal Impeller

HIDROSTAL TECH

The Screw Centrifugal Impeller

Hidrostal’s original screw centrifugal impeller combines axial and centrifugal flow in a single-vane, open-channel design. It helps pass rags, fibres and solids across a wide range of wastewater jobs.

How it works:

  • Open channel design for freer solids passage.
  • Lower turbulence to reduce wear and clogging.
  • Continuous flow path limits debris build-up.

FAQ – Hidrostal Wastewater Pumps

What makes Hidrostal pumps different from other wastewater pumps?

Hidrostal pumps use the original screw centrifugal impeller, designed to pass solids, rags and fibrous material with less risk of blockage – while also handling sludge and shear-sensitive fluids more gently.

Are Hidrostal pumps suitable for sludge pumping?

Yes. Hidrostal pumps are well suited to sludge pumping because their screw centrifugal impeller provides gentler handling and can manage thickened sludge with less risk of blockage.

Can Hidrostal pumps handle wipes and rags?

Yes. Hidrostal pumps are designed to pass wipes, rags and other fibrous material with less risk of blockage – which is a key reason why they're used in difficult wastewater jobs.

Where are Hidrostal pumps used?

Hidrostal pumps are used across:

  • Wastewater treatment plants
  • Pump stations
  • Industrial wastewater systems.
Do Hidrostal pumps improve energy efficiency?

Hidrostal pumps are designed to maintain high efficiency across a broad operating range – which can help reduce energy consumption when selected for the right project.

What is HydroMix technology?

HidroMix is an external pump-driven mixing system that recirculates sludge through strategically positioned nozzles to keep solids suspended and prevent settlement in tanks and digesters.
