PRESSURE SWITCH: SK-2

Performance Range
The SK-2 is a mechanical type of pressure switch used to control electric driven domestic type pumps. When the internal pressure of the pipe is more than the setting pressure, the pressure control will disconnect the load power supply to the pump and connect the power again when pressure drops below the set pressure. The SK-2 has two operating points; one on the rising pressure trip point and the other on the falling pressure (reset point). The differential is the difference in pressure between the trip point (cut-out) and the reset point (cut-in).

Operating Limits
Ambient Temperature: 0 - 55°C (but not frozen)

Technical Features
Rated Voltage: 220VAC, 50Hz
Maximum current: 12 Amp
Protection grade: IP20
Pre-set on-off pressure: 1.4 - 2.8bar
Maximum pressure: 6bar
Joint screw: G1/4”

PRESSURE TANKS: BLADDER TYPE

Performance Range
The bladder type series of pressure tanks is designed to provide reliable storage for pressurized water in a booster pump system. The pressure tank effectively releases its stored volume of pressurised water on demand and prevents pump start-ups for demands lower than its storage capacity. The internal bladder ensures that there is no contact between the water and the air.

Operating Limits
Liquid Temperature
EPDM 0°C to 99°C
Ambient Temperature up to 45°C
Max. Working Pressure 10 bar

Technical Features
Material Carbon Steel
Bladder EPDM
Orientation Vertical or horizontal
Connections 1” - 11/4” BSP
Capacity 24l, 60l, 100l, 300l

FLOW CONTROL SWITCH: SKD-2

Performance Range
Flow from 0 to 6m3/h. The SKD-2 flow control starts the pump automatically
when pressure decreases (for example taps are opened) and stops it when there is no flow/water shortage (for example taps are closed). It can be used for drinking water or non-portable water piping systems.

Operating limits
Pipe Water Temperature 0 - 60°C (but not frozen)
Ambient Temperature 0 - 45°C

Technical Features
Rated Voltage: 220VAC, 50Hz
Maximum current: 10 Amp
Protection grade: IP65
Starting pressure: 1.5bar
Maximum pressure: 10bar
Inlet/outlet size: (1" x 1") BSP

REPLACEABLE PC BOARD

FLOW CONTROL SWITCH: SKD-11

Performance Range
Flow from 0 to 15m3/h. The SKD-11 flow control starts the pump automatically when pressure decreases (for example taps are opened) and stops it when there is no flow/water shortage (for example taps are
closed). It can be used for drinking water or nonpotable water piping systems.

Operating limits
Pipe Water Temperature 0 - 60°C (not frozen)
Ambient Temperature 0 - 45°C

Technical Features
Rated Voltage: 220VAC, 50Hz
Maximum current: 30 Amp
Protection grade: IP65
Starting pressure: 1.2bar
Maximum pressure: 10bar
Inlet/outlet size: (1¼” x 1¼”) BSP
