Compact wet rotor electronic circulator with bronze pump body engineered for the circulation of domestic hot water in commercial building service. This product is manufactured by Dab. It is equipped with an integrated variable frequency drive to ensure better all-round performance and energy efficiency, it also protects the system against water hammer action.

Product Applications

Hot or cold water circulation pump with in-line ports, appropriate for installation directly on the pipework of civil and industrial heating, air conditioning, refrigeration, and sanitary water systems.

Construction Features Of The Pump

Pump body and motor support in Cast Iron. This product is manufactured by Dab. PN 10 flanged suction and delivery ports with threaded holes for control manometers. To make replacement in existing systems easier, the pump can accept PN 6 counter flanges. Technopolymer impeller. Carbon/ceramic mechanical seal. The pumps are available both in the single (KLM-KLP) and in the twin (DKLM-DKLP) versions.

For the twin version a built in clapet valve in the delivery port is also included, to avoid water recirculation when the unit is idle. A blind flange is also supplied as a standard, to be applied during maintenance of one of the two motors. The twin version gives the possibility of alternating the operation of the pumps when a backup unit is required, or to have the two pumps operating simultaneously.

Construction Features Of The Motor

External ventilation cooling, closed, asynchronous type, with four poles for the KLM and DKLM versions, and two poles for the KLP and DKLP versions. Rotor running on permanently lubricated ball bearings, oversized to ensure low noise and durability.

Standard built-in thermo-amperometric protection. Capacitor permanently fitted on single phase versions. For the protection of the three-phase motor, we recommend the use of remote overload cut-outs, in compliance with current local regulations. Construction according to CEI 2-3. Protection class: IP 55 Insulation class: F Standard voltage: single-phase 220-240 V, 50 Hz - three-phase 230/400 V, 50 Hz

ALPHA1 20-40 N 150

Grundfos ALPHA1 high-efficiency circulator pumps are designed for circulating liquids in heating systems. The stainless-steel variant of ALPHA1 is appropriate for, for example, domestic hot-water systems. With an energy efficiency index (EEI) at the ErP benchmark for most high-efficiency pumps, it contributes to energy savings.

The pump can operate in proportional-pressure, constant-pressure and constant-curve mode. The control mode is selected using the button on the display. The LEDs indicate the operating status, actual power consumption in watts as well as warnings and alarms.

The design and materials of the pump contribute to a long service life. The pump is self-venting through the system, which contributes to straightforward commissioning. The space-efficient design, featuring a pump head with an integrated control box, fits into most common installations. The pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These design features ensure maintenance-free operation.

Pump housings made of Cast Iron are electrocoated to improve corrosion resistance. The motor is a synchronous permanent-magnet/space-efficient-stator motor characterised by high efficiency. Pump speed is controlled by an integrated frequency converter incorporated in the control box.

Pumps are supplied with insulating shells to minimise heat loss in heating systems.
