The SI 1850 pump is designed to evacuate heavy and contaminated condensates. Capable of evacuating up to 1100 l/h, the SI 1850 pump is suitable for air conditioning units and industrial refrigeration displays. Strong, the SI 1850 tolerates charged, high temperature and acidic condensates (pH>3.4) produced by gas condensing boilers

The compact, sleek design of the Omega Pack is the ideal choice for  convenient under unit mounting.  The onboard Si-20 provides you Sauermann's high performance pumping capacities, yet with ultra quiet operation.

Peristaltic pumps* help lift charged condensates. Among the most compact on the market, they combine silence with a practical and clever design : detachable and replaceable head and tube = optimised maintenance and cost.
The PE5100 operates by detecting a 6°C temperature change via two temperature probes located in the air on and air off position. * These pumps must not operate continuously

Among the most compact on the market, they combine low operating sound level with a practical and clever design : detachable and replaceable head and tube = optimised maintenance and cost. The PE 5200 controlled by a remote detection unit fitted with a 3 level float.

The versatile SI 2052 is suitable for replacement of some market standards drain pumps used in cassette type air-conditioning units up to 20 kW.

The centrifugal technology inside this pump is specifically designed for removing condensates continuously, in any kind of environment, with a very low sound level.

The single level detection unit can be used as a safety contact (NC) to cut off the air conditioning system compressor or a solenoid valve automatically.

The distinctive shape of the new Si-10 UNIVERS’ L pump allows it's use in both new installations and refurbishments.
The improved pump ensures a reduced sound level and the new design offers ease of maintenance.

The SI 1805 pump is designed to be easily installed whatever the layout of the premises. Capable of evacuating up to 500 l/h, the SI 1805 pump is suitable for air conditioning units and industrial refrigeration displays. Strong, the SI 1805 tolerates charged, high temperature and acidic condensates (pH>3.4) produced by gas condensing boilers.

Complete kit intended for wall mounted air conditioning units. Includes; a new elbow design that can be easily opened by hand by a simple finger push - no tool is needed and the Si-10 UNIVERS’L pump which incorporates the latest in piston pump technology. The Delta Pack's streamlined design complements wall mounted air conditioning units. Low sound level and highly resistance to pollution created by the general environment.

The SI 1830 is a centrifugal tank pump with IPX4 protection.

The pump has been designed to be capable of processing acidic (pH> 2) & high temperature condensates (80°C max) and can be used on oil boilers.

With a range of up to 400 l / h, the SI 1830 is also ideal for air conditioners and refrigerated display cases.
