Choosing the right pump model for your specific requirements.
Bronze in-line pumps and suitability
Kolmeks in-line constant speed pumps (AP, AEP, ALP, LP and those with IEC motors with the additional designation SD) as well as pumps with integrated frequency converters (SC, MD, NC) are made of bronze, which makes them suitable for, among other things:
- Hot water
- Chlorinated water
- Closed and open systems
- Cooling circuits
- Industrial systems
In-line pump design and motor technology
In-line pumps are centrifugal pumps designed for pumping purposes and equipped with Kolmeks or IEC dry motors (additional marking SD), in monoblock construction, meeting the requirements of the EcoDesign directive. The electric motor has high efficiency, quiet running noise and is suitable for frequency converter use. The bearings of the electric motors are permanently lubricated and maintenance-free. The pumps can also be equipped with an SC, MD or NC series frequency converter integrated onto the electric motor.
The impeller of the pump with a Kolmeks motor is mounted directly on the shaft of the electric motor (separate clutch in SD) and is a highly energy-efficient and reliable design.
KC domestic water pumps
In addition, our range includes electronically controlled, high-efficiency domestic water pumps.
The KC SAM / SAS II pump has a stainless steel housing. The pumps can be used as circulation and transfer pumps for clean liquids.
The rotor package is made of one piece without welding, the rotor casing is made of stainless steel AISI 316, the pump shaft is made of stainless steel AISI 316. The impeller is made of synthetic material reinforced with glass fiber PES GF30. The bearings are made of graphite. The SAS II pump series is available with a wide range of automation interfaces, for example with the C-additional module the most common bus interfaces.
Smart flow everywhere – Kolmeks hot water pumps with a wide operating range
Advantages of Kolmeks VFD pumps:
- The pump adjusts to the system, ensuring silent operation.
- Pumping capacity is based on actual demand, resulting in lower lifecycle costs.
- Payback period compared to a fixed speed pump is 0.5–2.5 years depending on the model (see example chart).
- Alarms can be connected to external systems.
- The operating point can be precisely adjusted (domestic hot water).
- Operates according to system conditions (radiator and ventilation circulation).
- Energy saving.
- Robust and reliable.
- Extended pipeline network lifetime.
- MD and NC inverter pumps can also be safely controlled remotely via Bluetooth connection.
