• Condensate inlet and outlet ______________ similar to EN 1092-1

Type 02/35-PN16, DN40 and DN50

Union with butt weld ends (optional):

• Condensate inlet and outlet ______________ DN25 with butt weld ends 33,7 x 2,6

DN40 with butt weld ends 48,3 x 2,6 DN50 with butt weld ends 60,3 x 2,9

• Motive medium _______________________ DN15 with butt weld ends 21,3 x 2,0

Features
• Automatic operation, adapts automatically to the condensate level and the pressure conditions

• No manual settings required

• Robust, durable design

• Easy servicing, no need to disturb the pipework for maintenance and repairs

• All internals made of stainless steel, wearing parts in hardened stainless steel

• High-endurance Inconel X-750 springs

• Body designed with high cycle fatigue strength

• Low filling head

• No leakage due to moving exterior parts

• Works without electricity

• Connections: Female thread Rp/G, union with butt weld ends or loose flange available as an option (loose flange only for main connections)

Fluids pumped
• Group 2 fluids with a density of 0,85 to 1,15 kg/dm³
Mounting position
• Standard: Horizontal Required filling head above pump trap footprint:

• min. 300 mm

• required: 500 – 1200 mm

1) The operating pressure refers both to the maximum pressure of the motive medium and to the maximum pressure of the condensate upstream of the pump trap.
2) The allowable differential pressure refers to the difference between the maximum pressure of the condensate upstream of the pump trap and the minimum possible back pressure.
3) The maximum possible back pressure is 5 bar. Back pressures higher than 5 bar require consultation with the manufacturer.

Attention!

The design data is not the same as the operating data. The specified operating limits (PS, TS, ∆PMX) must not be exceeded. Exceeding the operating data can result in malfunctions or impair safety

The maximum test pressure for the shell strength and seat tightness tests is 32 bar at room temperature.
