CSE TC W iPWM MFB PUMP STATION

│2
1. Introduction
CSE TC W iPWM MFB pump station is designed to be installed on the return pipe to the heat pump,
where it ensures circulation through the heat pump circuit. The circulation pump is switched by an
external controller, the pump speed controlled by PWM signal. With no PWM signal the pump runs
at max. speed. The pump station includes 2 ball valves, one of them with integrated strainer and
magnet. The strainer can be easily removed and cleaned without any tools. The pump station is
designed for installation directly on a pipe with a min. pipe centre distance from a wall of 100 mm.
2. Description of the pump station
The pump station consists of aWilo PARA 25/8 iPWM1 130mm, ball valve w. filter and magnet,
thermometer, insulation.

4. Wilo-Para iPWM1 Pump
4.1. General Information
The Wilo Para 25/8 iPWM1 is a wet running
circulation pump. The pump speed is controlled
by the PWM signal. When the PWM signal is
disconnected, the pump runs at its maximum
speed. The operating status and possible faults
of the pump are indicated by LEDs directly on
the pump. The pump can send the current flow
rate electronically to an external controller. The
controller needs to be equipped with an iPWM
read input and a flow rate calculation function.
The high efficiency circulation pumps of the PARA
iPWM1 series are used exclusively for the circula-
tion of liquids in hot water heating systems. Ope-
rating the pump in other systems or in systems
containing too little water, air bubbles or not pres-
surized can lead to its rapid destruction.

5. Ball Valve w. filter & magnet
5.1. Maintenance and cleaning
1. Close the ball valve by turning the lever clockwise by 90° (Fig. 1).
2. Unscrew the lid with magnet manually and take out the strainer (Fig. 2, 3).
3. Remove impurities from the strainer and magnet.
4. Return the clean strainer back to its place and screw on the lid with magnet.
3. Open the ball valve by turning the lever counter-clockwise by 90° (Fig. 4).
