Lowara Sekamatik 50

Sekamatik 50 is a compact, cost effective and odor free solution for handling domestic wastewater in buildings.

It's the ideal solution whenever sanitary appliances are located at a lower level than the main gravity sewer system.

The grinder pumps macerate incoming particles, allowing the use of small pipe diameters. This and the compact footprint make the Sekamatik 50 easy to install and ideal to use in buildings away from the main sewer line.

The Sekamatik 50 operates fully automatic and up to three sanitary units can be connected.

Designed in accordance with EN 12050.

Lowara Sekamatik Wastewater Lifting Stations

Sekamatik series is a range of grey / rain water or sewage lifting stations ideal for larger private or public buildings. Motor power up to 11.5 kW with capacities up to 200 m3/h and storage tanks are available in plastic with volumes from 180 up to 800 liters.

The compact design allows an installation with minimum space requirement. Sekamatik 10 E 7M is a compact behind the toilet pumping station with cutter pump. Install a toilet anywhere, typically without any major construction.

Sekamatik 50E (single pump), Sekamatik 50D (twin pump)

COMPACT SEWAGE DISPOSAL UNIT WITH SUBMERSIBLE WASTEWATER PUMPS WITH GRINDER SYSTEM

The Sekamatik 50E and Sekamatik 50D are versatile compact sewage disposal units suitable for removing dirty water and effluent where gravity drainage is not possible. They are used for pumping sewage and wastewater from toilets, hand basins, showers and rooms which are below the sewer level (see DIN EN 12056), or where small discharge pipes are necessary such as under difficult topographic conditions or areas of low population.

With the advantage of using discharge pipes of either DN 40 or DN 50 diameters, reduced construction work and cost is possible compared to conventional discharge pipes. They are available as a single pump station (Sekamatik 50E) or as a twin pump station (Sekamatik 50D).

DIN EN 12050-3: Conformity and design approved and controlled by LGA.

Pumped liquid: Wastewater or sewage containing soft solids. Max. liquid temperature: 35°C short term up to 60°C.

Operation: Intermittent.

Controls

Pneumatic level control with pressure control. Electronic control box for control, monitoring and notification of all important functions with advice of any problems. Motor protection with temperature control of the winding. Optical indication of unit failure. Alarm signal through integral buzzer. Volt-free contact for remote signal. Control indication for direction of rotation. Motor overrun period which prevents sewage build up and blockage. Easy conversion to mains independent alarm via 9,0 V battery installation. Additionally for twin pump station Sekamatik 50D: Auto-change over after each pump cycle. Operation of second pump at high flow. In the event of failure one pump automatically changes to the second pump.
