Pedrollo PQm-Bs peripheral electric pumps operate with an efficient and reliable single-phase motor, which is distinguished by the following characteristics:

• Motor housing: aluminum
• Silent operation
• Air-cooled
• Equipped with thermal protection and a built-in capacitor
• Protection class: IP X4
• Insulation class: F 

The hydraulic components of Pedrollo PQm peripheral pumps are made from the most durable and corrosion-resistant materials:

• Pump body:Brass with threaded holes
• Shaft:Stainless steel
• Frame:Aluminum with brass-finished front (this allows for better starting after a long period of pump inactivity)
• Peripheral impeller:Brass (has radial blades that automatically adjust to the shaft)
• Mechanical seal:Silicon carbide-graphite

Pedrollo's PQm-BS series electric pumps are distinguished by their monobloc construction, meaning that the electric motor that drives the pump and the hydraulic suction are housed in a single location and mounted on a single shaft. The use of innovative design and technological solutions ensures the efficient and long-term operation of the pumps.
