Four impeller geometries developed in-house. Drag any model to turn it; switch between the impeller alone and the complete unit.

UPP JF-2

Jet-Flow Impeller

Deep-tank circulation · long-reach axial flow

Blades	Two blades
Profile	High axial jet

A two-blade jet-flow impeller that generates a concentrated axial flow with extended pumping reach, for deep tanks with relatively small diameters and a high liquid depth-to-diameter ratio. Installed at several levels on a common shaft, JF-2 impellers establish a strong vertical circulation pattern through the full tank height — the hydraulic effect of a draft tube, without a physical draft tube.

Sludge conditioning
Vertical circulation over long distances

UPP ARH-3

Anti-Ragging Hydrofoil Impeller

Rag-resistant · high axial circulation

Blades	Three blades
Profile	Swept-back hydrofoil

A three-blade anti-ragging hydrofoil for fluids carrying fibrous and stringy material. The swept-back geometry and continuous, smooth leading edge let hair, fibre and textile slide outward along the blade instead of accumulating around blade and hub, while keeping strong axial circulation.

Anoxic and anaerobic tanks
Equalisation tanks
Fibre-bearing industrial wastewater

UPP EAF-3

Efficient Axial-Flow Impeller

High flow · low power · low shear

Blades	Three blades
Profile	Narrow-profile hydrofoil

A three-blade, narrow-profile axial-flow impeller that delivers high pumping capacity for low power input: high circulation, low power number, low shear, high pumping efficiency. The general-purpose choice where energy-efficient circulation and uniform mixing are the process requirement.

Equalisation and homogenisation
Flocculation
Low-to-moderate solids suspension

UPP HSF-4

High-Solidity Flow Impeller

High thrust · low tip speed · heavy-duty solids suspension

Blades	Four blades
Profile	Wide-profile axial

A four-blade, wide-profile axial impeller with a large effective blade area, producing high pumping capacity and strong axial thrust at relatively low rotational speed and tip velocity. Effective solids suspension and bottom sweeping in dense, rapidly settling or abrasive slurries.
