Solenoid-driven diaphragm metering pumps

Diaphragm dosing pumps are leak-free, and are therefore suitable for highly aggressive or toxic media. Depending on the gear type, the diaphragm allows pressures up to 232 psig. Diaphragm dosing pumps are fitted with a separation chamber as standard. If a crack forms in the diaphragm due to wear, this prevents the medium from flooding the system components or the pump itself. The medium is controlled and flows through a downpipe to the collecting basin. The medium sides of the diaphragms are coated with PTFE.

MAGDOS LB, LD, LA, LK, LP, DE, DX


Simple to use and space-saving: Our MAGDOS solenoid-driven diaphragm metering pumps

The solenoid-driven diaphragm metering pumps MAGDOS stands for dosing without compromises. Thanks to a number of the various pump types there is the right individual solution for every application, also for the highest demands.

Depending on the area in which they are used, different materials and connecting elements can be used on both the suction and discharge side of solenoid diaphragm dosing pumps. Special accessories are available to achieve the best possible results and ensure quick installation.

MEMDOS LB
Description:Riding on the crest of the waves The MEMDOS LB is used when the integration of the pump into controls or control circuits is required. Thanks to the sturdy tappet drive with manual or automatic capacity adjustment, the conveyed media such as acids, lyes, coagulants and flocculants are dosed reliably and precisely. To adapt the dosing capacity, either the stroke length can be adjusted mechanically or the speed of the three-phase motor can be regulated by means of a separate frequency converter. On request, the MEMDOS LB pumps can also be supplied with a double-diaphragm system.Features & advantages: Capacity range 1.06 – 324 gph, up to 232 psig Power supply 115 V, 230 V or 400 V Material finishes PVC, PP, PVDF and stainless steel Infinitely variable stroke length from 0 – 100 % A variety of three-phase and alternating current motors ATEX versions are available for Zones 1 and 2 Also suitable for frequency converter operation Double-diaphragm system (optional) Automatic stroke length adjustment (optional) MEMDOS LB 44-HP1010-HP2020-HP356080150 Delivery capacity at max. pressure50 Hzgph 1.062.223.706.355.829.5216.6723.8141.27 60 Hz 1.32.74.47.67.011.4202950 Max. back pressurepsig 17423217423217423214572 Nominal stroke frequency 50 HzRPM 26721207212072120 60 Hz 31.286.414486.414486.4144 Suction lift for non-gassing mediaft H2O 292623 Max. supply / inlet pressurepsig 7.3 Diameter of diaphragmin 2.0472.5193.543 Valve size DN4DN6DN10 Voltage supply 230 / 400 V (optional 115 V) Protection class IP55 Insulation class F Material PP, PVC, PVDF, 1.4571 Weight* PPlb 11.511.115 PVC 11.111.114.1 PVDF 11.911.915 Stainless steel (1.4571) 17.617.626.5 Max. ambient temperature°F 316SS & PVDF: 113° / PVC: 104° Max. temperature of the medium°F 316SS & PVDF: 176° / PP: 140° / PVC: 95° MEMDOS LB 1101602102603104005107601010 Delivery capacity at max. pressure50 Hzgph 30.238.155.669.877.8103.2133.3196.8269.8 60 Hz 3646678493124160236324 Max. back pressurepsig 145116875844 Nominal stroke frequency 50 HzRPM 9612096120961205376107 60 Hz 115.2144115.2144115.214463.691.2128.4 Suction lift for non-gassing mediaft H2O 2319143 Max. supply / inlet pressurepsig 7.3 Diameter of diaphragmin 3.5434.7245.9057.283 Valve size DN10DN15DN25 Voltage supply 230 / 400 V (optional 115 V) Protection class IP55 Insulation class F Material PP, PVC, PVDF, 1.4571 Weight*PPlb 25.327.531.745.8 PVC 25.327.531.745.8 PVDF 26.028.633.549.6 Stainless steel (1.4571) 36.846.557.793.2 Max. ambient temperature°F 316SS & PVDF: 113° / PVC: 104° Max. temperature of the medium°F 316SS & PVDF: 176° / PP: 140° / PVC: 95° Downloadshttps://www.lutzjescoamerica.com/fileadmin/data/dokumente/pg1/LJ-MEMDOS_LB-EN-BA.pdfhttps://www.lutzjescoamerica.com/fileadmin/data/data_usa/documents/pg1/Spec_Sheet-MEMDOS_LB.pdfhttps://www.lutzjescoamerica.com/fileadmin/data/data_usa/documents/pg1/Spec_Sheet-MEMDOS_LB-Spanish.pdf
