MP 1, SQE-NE, SPA-NE, SP-NE - SCL Water

General dataMonitor pumpMP 1ApplicationsThe MP 1 is designed for the pumping of contaminated/polluted groundwater for• purging• sampling• water quality monitoring.The MP 1 has been specially developed for sampling,i.e. pumping of small quantities of water to be sent tothe laboratory for analysis in order to establish• content of contaminants• concentration of contaminants• extension of contamination plume.The MP 1 pump is made of inert materials, which do notaffect the pumped liquid and thus the analysis results.The pump performance is adjusted by means of theconverter which controls the pump speed via thefrequency. In this way a steady, airfree water flow canbe achieved.The MP 1 offers efficient purging of the well beforesampling as a high pump performance is achievedwhen the frequency is raised. Maximum performance isat 400 Hz.However, the pump must not pump more water than thewell can yield. Otherwise, the water table may fall to alevel below the suction interconnector and air will besucked into the pump. Besides reducing the cooling ofthe motor, this situation may damage the pump. Inorder to avoid cleaning of the pump and possible crosscontamination,i.e. transfer of contaminants from onewell to another, dedicated installation of the pump isrecommended.This also saves valuable time for the samplingtechnician as he can quickly disconnect the converterand proceed to the next MP 1 installation. Thesubmersible drop cable is connected to the convertervia a plug connection so that disconnection is possiblewithout the use of tools.Fig. 4 MP 1 with converterType keyExample MP 1Monitor pumpRated flow[m 3 /h]Gr3101 - GrA60967
