ACO Marine Data sheet ACO PowerVAC - Vacuum Generation & Wastewater Transfer Units The ACO PowerVAC vacuum pumping unit forms the centrepiece of the centralised vacuum toilet collection and transfer system. The ACO PowerVAC unit is designed to create a powerful vacuum within the vacuum line network to ensure efficient and reliable wastewater collection and transfer. The positive displacement pumping principle allows a transfer of wastewater directly to a wastewater treatment plant or holding tank without the need for a temporary collection reservoir. The compact, close-coupled pump design provides a small footprint which makes the unit ideal where space is limited. The ACO PowerVAC unit is simple to install and service thanks to its compact and well thought-out Easy-to-Maintain design. ACO PowerVAC - Efficient & flexible vacuum generation & sewage transfer units for marine applications ▪ Designed for vacuum toilet, black water collection systems & wastewater transfer ▪ Powerful vacuum generating and two-phase wastewater/ air pumping unit. ▪ Different models and pump capacities available including high-head wastewater transfer pump options. ▪ Robust & reliable pump design with close coupled electric drive. ▪ High quality pump materials & cartridge type mechanical seal system. ▪ Pumps are designed according to the easy-to-maintain principle. Easy access to the pumping elements, wear parts and sealing system by simply removing the ‘wet end’ pump cover Process description The pump head provides two intermeshed rotors which are each fixed to a gear driven shaft. The shafts rotate in opposite directions. The rotating motion of the rotors creates an expanding cavity on the suction side which maintains a strong vacuum at the inlet of the pump. Wastewater and air enter and fill the suction side of the pump. The rotors carry the twophase fluid around the housing to the discharge side where it is expelled out of the pump by the closing cavity. The PowerVAC units are self-priming and insensitive to dryrunning and foreign objects. Therefore there is no requirement for macerating of black water in front of the pump which can improve the solid separation process i
