For the Medana CH1-L series:

• Impellers, guide vanes, stage housing made of stainless steel 1.4301
• Pump housing made of 1.4301 stainless steel
• Shaft of made of 1.4301 stainless steel
• O-ring seals made of EPDM

Base frame: made of galvanised steel, to be fastened to a concrete foundation

Pipework: Complete pipework of stainless steel, suitable for the connection of all standard pipe materials; the pipework is designed according to the hydraulic output of the pressure-boosting system.

Pumps: Two pumps of the Medana CH1-L series connected in parallel; all wetted pump components are made of stainless steel. ACS approval for all components that come into contact with the fluid.

Valves: Each pump is equipped with an ACS-approved ball shut-off valve on the suction and discharge side

Diaphragm pressure vessel: A diaphragm expansion tank must be designed in accordance with the installation conditions and provided on-site

Pressure indication: On the pressure gauge on the discharge side and on the display of the ElectronicControl

Switchgear: The system is standard-equipped with an ElectronicControl per pump in master/slave mode.

• Factory-mounted, ready for connection pressure-boosting system checked for functionality and impermeability
• Installation and operating instructions

Pressure reducer

Excessively high or strongly fluctuating inlet pressure requires the installation of a pressure reducer to maintain a constant minimum inlet pressure level. The maximum permissible fluctuation of the inlet pressure is 1.0 bar.

Volume flow

Up to 16 m³/h (4.4 l/s) maximum volume flow when two pumps are in operation.

Inlet pressure

The maximum inlet pressure (see Technical data) is to be observed for the system configuration. The maximum inlet pressure is calculated from the maximum unit working pressure minus the maximum pump delivery head at Q = 0.
