Pedrollo GP3W - MK Variable Speed Pumping Units

GPW is a pre-assembled system designed to connect to water mains or a primary collection tanks. It provides wa- ter supply and pressurization and is ideal for residential, commercial, and public buildings. It's also suitable for ho- tels, park irrigation, as well as industrial water handling and treatment.

GPW is compatible with clean water and aqueous solutions that do not chemically or mechanically harm the materials used and are free from abrasive or fibrous substances.

Product Description

GPW is a variable speed pressurization system comprising two or three pumps assembled into one unit. It is electronically controlled by two or three STEADYPRES devices connected in parallel. These devices automatically adjust the pump operation based on the system's varying water demands, ensuring constant pressure.

When water withdrawal reduces the system pressure, the first pump activates to meet the required flow rate, maintaining pressure at the set value. As the maximum rotation speed is reached, additional pumps start up in sequence to fufil the system's water demand.

Components

Pumps connected in parallel via suction and discharge manifolds. Each pump is equipped with a ball valve on the suction side and a ball valve and non-return valve (integrated in STEADYPRES) on the discharge side.

BASE made of metal profile and equipped with adjust- able vibration-damping feet. 

STEADYPRES ELECTRONIC DEVICES installed directly on the delivery pipe of each individual pump. They continuously regulate the rotation speed, ensuring a constant pressure even as user demands fluctuate. Each inverter can manage the alternating operation of pumps as needed.

GPW is designed to protect the system from:

• Dry running
• Overvoltage and undervoltage

CONTROL PANEL equipped equipped with magnetothermal mo- tor protection circuit breakers for three-phase versions, and magnetothermal circuit breakers for single-phase versions.

GP3W – MK

Pressurization units comprising three vertical multistage pumps equipped with STEADYPRES inverters capable of maintaining constant pressure in the system. GP3W - MK are suitable for residential, commercial, and public water supply, large- scale irrigation, and handling clean water in general.
