Pedrollo PQ90 electric pump

Pedrollo PQ90 is a high‐efficiency vortex pump with a compact casing and streamlined design, specifically engineered to generate high pressure at moderate flow rates. It is ideal for systems requiring stable water pressure at low flow, making it particularly effective in residential, commercial, and technical installations.

Technical Operating Principle:
The PQ90 employs a vortex compression principle, where water repeatedly circulates between the impeller’s radial vanes and the pump’s internal channels. This process accumulates energy and produces high pressure even at lower flows. The technology delivers a smooth, pulsation‐free flow—critical for sensitive systems.

Construction Features:
▪️ Vortex impeller with numerous radial vanes
▪️ Precision‐machined components to minimize vibration and extend service life
▪️ Casing made from durable, moisture‐resistant materials
▪️ Stainless‐steel shaft with fully sealed mechanical seal
▪️ Motor with built‐in thermal protection and air cooling

Applications:
▪️ Water‐supply and pressure‐boosting systems in private homes and apartment buildings
▪️ Washdown stations, including professional setups
▪️ HVAC, cooling, and reverse‐osmosis systems
▪️ Industrial complexes requiring precise dosing or stabilized pressure
▪️ Professional ironing and boiler units

Advantages:
▪️ Delivers high, stable pressure from a compact footprint
▪️ Continuous operation without overheating
▪️ Low noise level—for comfort near living spaces
▪️ Universal connectivity and easy maintenance

Installation Recommendations:
Install indoors or under shelters that protect against rain, dust, and extreme temperature fluctuations. Ensure adequate space for ventilation and routine maintenance access. Operates only with clean, non‐abrasive water free of sand or particles.
