The Hydro MPC-E features a booster set of pumps and motors with integrated frequency converters. The Hydro MPC-E makes sure that the ﬂow and the pressure are continuously adapted to the system demands to make your system highly efficient. The procedure usually consists of 2 to 6 identical pumps in parallel, mounted on a base frame and connected to a control cabinet.
At the heart of the Hydro MPC, booster system is the CU352, a multi-pump controller. The CU352 controls how many pumps should be in operation at any given time and controls the speed of the individual pump. The advanced controller optimizes the performance of the booster system to minimize energy loss.
CU352 performs a complex task, and installing and operating the unit is simple. The installation wizard guides the installer through a series of steps until the booster system is correctly installed and commissioned. The installation process is performed by following the on-screen instructions of the control unit. The simple, user-friendly interface ensures that the day-to-day operation is equally easy.

The Grundfos KP horizontal split-case pump is a single-stage, between-bearing, double-suction pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipework. The independent bearing housing allows for ease of maintenance without removing the top casing.
The double volute design reduces the radial load on the shaft, extending component life, minimizing vibration and providing quiet operation.
The Grundfos LC is a close-coupled centrifugal end suction pump in a compact design for optimized space savings. The Grundfos LF version is the same pump but in a frame-mounted format for added durability. Both LC and LF pumps offer high efficiency, and their double volute design lowers lifecycle costs and prolongs seal and bearing life. NSF61/50 certification is available.
Grundfos LCS is a single-stage, end suction, split coupled, base mounted centrifugal pump. Its smaller footprint with no alignment and grouting requirement in the field makes it a unique pump design. The pump features axially split coupling, capable of withstanding all torsional, axial, and radial loads.
The single-stage pumps offer robust and reliable operation in a compact, vertically mounted frame. The pump’s double volute design balances radial loads while extending the life of wear rings, shaft seals and bearings. These pumps are highly customizable and perfect for retrofits or specialized applications in small spaces, with many material options.
