EBARA BEST 2 MA

Stainless Steel Submersible Pump for clear and waste water with 10m cable 230V|1Ph|50Hz| P1= 0.98kW| P2= 0.55kW| I=4.4A discharge outlet: 1½“ (FT) with automatic level control 10 mm solids passage T(max)=50°C H(max)=13.1 m | Q(max)=15.6 m³/h Submergence(max)=10m TÜV/GS-certified | WEEE-certified | CE | Made in EU   The EBARA BEST 2 MA is a fully stainless-steel submersible pump with float-switch for automatic level control operation. It is used in sump pump chambers for applications such as general drainage as well as wastewater & sewage water handling with a solids passage of up to 10mm.   With a maximum volume capacity of 260 litres per minute and a maximum pumping head of 13.1 metres, the EBARA BEST 2 MA is used in commercial and agricultural installations, where higher pumping volume is required, and in private domestic installations with prolonged pumping distances.   Applications include draining wells, garages, cellars or places subject to flooding. Wastewater Treatment System & Septic Tank Pump The EBARA BEST 2 MA is used to pump treated effluent in domestic treatment sytems and septic tanks where the subsoil polishing filter area or percolation area are not located in close proximity to the final effluent chamber. The higher performance and pumping height of the pump compensates the pressure loss involved with longer pipe distances and ensures the final effluent chamber is sufficiently emptied during pumping intervals.   Regular maintenance of your wastewater treatment system or septic tank & good practice ensure sufficient treatment levels in the final effluent chamber. This is also important in order to achieve a satisfactory lifespan of the submersible pump.   A general guideline to wastewater treatment systems & servicing, including replacement of the submersible effluent pump, is available for download in pdf-Format: GUIDE – Wastewater Treatment Systems

Replacing the septic tank pump is therefore usually an urgent matter, as system backlog and potential overflowing with contamination to the surrounding ground area should be avoided.   Regular maintenance of your wastewater treatment system or septic tank & good practice ensure sufficient treatment levels in the final effluent chamber. This is also important in order to achieve a satisfactory lifespan of the submersible pump.   A general guideline to wastewater treatment systems & servicing, including replacement of the submersible effluent pump, is available for download in pdf-Format: GUIDE – Wastewater Treatment Systems Non-return flap valve - included as standard The non-return flap valve can be easily included to the pump discharge when fitting the pipe coupler. The non-return flap valve prevents water within the pipe from re-entering the pump and sump chamber after the pumping cycle has ended.  This can significantly reduce the number of pump starts, especially in smaller sump chambers with less volume.The non-return flap valve should not be included, if the discharge pipe is located in an environment subject to frost or sub-zero freezing temperatures. Quality Components Submersible pumps used numerously on a daily basis require quality components to ensure realiability and a long pump lifespan.  THE GEMAT 430 NS has robust stainless steel components, a mechanical seal (Ceramic/Carbon/NBR) as well as a glassfibre-reinforced impeller, diffuser & motor-cover in technopolymer.   The GEMAT 430 NS submersible sump pump is suitable for continuous duty operation.

GEMDISC Aeration Disc Diffuser | 325 mm
GEMDISC Disc Diffuser | 325 mm | EPDM

Aeration Disc DiffuserMembrane Material: EPDM Material Plate & Securing Ring: PP Upper Diameter: 325 mm (300mm aeration) Lower Diameter: 330 mm Perforation: 1.0 mm | fully opened: ~ 200 mbarConnection: ¾“ MT Q(min): 2 Nm³/h | (Q(max): 12 Nm³/h Made in Germany   Fine bubble aeration with high oxygen-transfer is essential to obtain treatment level targets. It is recommended to evenly distribute GEMDISC disc diffusers within the aeration chamber (bio-reactor) for well-balanced fine bubble aeration.   The 12" disc diffuser with EPDM membrane ensures long-term reliable operation due to the valve-effect of the perforation, enabling both continuous as well as energy-efficient intermittent aeration intervals.   For effective operation and membrane longevity, air-input volume and pressure introduced into the disc diffuser should be (a) as high as is required for a good air bubble picture and (b) as low as possible.   The perforation of the membrane begins to open at approximately 40 mbar and is fully opened at ~ 200 mbar. After initial start-up (commissioning), it may be required to briefly operate at a moderately higher pressure level in order to allow the perforation over the full cross-section of the disc diffuser to open entirely.    The flexible and elastic membrane in EPDM is suitable for operation at wastewater treatment plants with predominantly domestic sewage combined with a light to moderate influx of industrial wastewater.   Areas of Application: municipal sewage & wastewater treatment plants decentralised remote sewage treatment systems domestic wastewater treatment systems aeration on landfill sites
