Further to the single pump-out units for wastewater and oil-contaminated wastewater also combined pump-out facilities are available in our delivery program. This configuration includes two suction inlets - one for sewage and the second for oilcontaminated wastewater - enclosed in one housing as a centralised sanitation system! In addition to our well-known combined pump type SKP, this new duo-pump has been introduced and produced. This combined pump-out station comes with one motor only, thus one control box, however, with two membranes. Two suction pipes and two discharge pipes are pumping two types of liquids to separate locations. As a result this duo-pump SPC-6 is very compact and practical for installation without sacrificing limited dock space. Each of the two suction heads is equipped with their own coin selector, pushbutton switch or Sep-key® reader, an on/off of key switch and user instruction text plate. The two suction inlets are flowing through the system completely separated, so no mixing of sewage wastewater and oil-contaminated wastewater is possible. The duo-pump may be equipped with a stainless steel foundation / drip tank for installation into the soil or on the pontoon. Oil leakage occurring during servicing runs into the drip tank and cannot pollute the soil or water!
