What is the difference between a monoblock and a standard end-suction pump?

Monoblock pumps have the impeller mounted directly on the motor shaft, eliminating the need for couplings and baseplates, resulting in a more compact design.

What are the primary applications for KM-type monoblock pumps?

They are primarily used in HVAC systems, industrial water supply, irrigation, and fire-fighting systems.

What are the benefits of choosing a close-coupled (monoblock) design?

Space-saving installation, no need for shaft alignment, lower noise/vibration, and more cost-effective compared to frame-mounted pumps.

How do I select the right monoblock pump for my system?

Selection is based on the duty point (flow and head requirements), liquid characteristics, and installation constraints.

FAQ: Monoblock End-Suction Pump Units

The main difference lies in the drive assembly. In monoblock pumps (KM type), the impeller is mounted directly onto the extended shaft of the electric motor. This eliminates the need for a coupling and a common baseplate, making the unit much more compact and easier to maintain since shaft alignment is not required.

Due to their reliability and small footprint, monoblock pumps are widely used in heating and cooling systems, industrial water supply, and transfer of technical water. They are also ideal for fire protection systems and agricultural irrigation.

Key benefits include significant space savings during installation, reduced vibration and noise due to the rigid connection, and a lower total cost because no baseplate or coupling is needed. This is the optimal solution for confined spaces like modular boiler rooms.

Ekvives experts perform selections based on your specific duty point: the required flow rate (Q) and head (H). We also consider the liquid temperature and the seal type (stuffing box or mechanical seal). All our pumps are certified and come with an official warranty.
