Modular Design Enables Customising

When con­sid­er­ing pump sys­tems, it is often the case that split­ting into a cas­cade of small designs is more flex­i­ble and more ener­gy-effi­cient than a sin­gle high per­for­mance pump. This is espe­cial­ly true against the back­ground that mod­u­lar­i­sa­tion in the process indus­try is an impor­tant devel­op­ment trend and, depend­ing on the con­fig­u­ra­tion, requires dif­fer­ent pump­ing capacities.
How­ev­er, there is also the oppo­site devel­op­ment: Con­ven­tion­al mono sys­tems that are still required for com­modi­ties only pay off when they reach a cer­tain size. And cor­re­spond­ing­ly high-per­for­mance pumps are required in these large-scale engi­neer­ing projects, in the pri­ma­ry process­es (reac­tant and prod­uct trans­port) as well as in sec­ondary process­es (cool­ing, rins­ing processes).
Of great impor­tance for the effi­cien­cy of these pumps: All ver­sions have a high­ly effi­cient dri­ve and can be equipped with an inte­grat­ed speed con­trol via a fre­quen­cy con­vert­er (CRE). Again, the oper­a­tor has the choice: Both the clas­sic MGE asyn­chro­nous motor (up to 22 kW – ener­gy effi­cien­cy class IE3) and the MGE per­ma­nent mag­net syn­chro­nous motor (up to 11 kW – ener­gy effi­cien­cy class IE5) have the fre­quen­cy con­vert­er inte­grat­ed in the motor. For high­er out­puts, the com­pa­ny offers the CUE solu­tion with an exter­nal fre­quen­cy con­vert­er in the con­trol cab­i­net – option­al­ly avail­able with IE5 motors. Each of these solu­tions increas­es the life of the pump and saves ener­gy as the boost­ing require­ment changes.
With 16 sizes (flow range between 0.3 and 355 m³/), four mate­r­i­al ver­sions (cast iron, two cor­ro­sion-resis­tant stain­less steel grades, tita­ni­um) and a range of dif­fer­ent con­nec­tion and equip­ment vari­ants, the oper­a­tor has the most diverse and com­pre­hen­sive range of pumps avail­able on the mar­ket. The pos­si­bil­i­ties for cus­tomis­ing have no lim­its. Also avail­able are 50 and 60 Hertz IEC motors as weel as 60 Hertz Nema motors.
The mod­u­lar design makes fur­ther cus­tomis­ing pos­si­ble. This specif­i­cal­ly means that the pumps can be indi­vid­u­al­ly equipped with few­er accessories/components on request; what the cus­tomer does not need is elim­i­nat­ed — this reduces the complexity.
