MEMDOS LA
Description:Riding on the crest of the waves The MEMDOS LA is equipped with a diverse range of inputs and outputs and can thus be deployed for complex dosing tasks. It can be controlled via a 0/4 – 20 mA current input and an external release input. At the same time, it indicates its current operating state via a fault output (alarm relay) and an optocoupler output (stroke feedback). The pump is fitted with a 0 – 20 mA analogue output. The MEMDOS LA is compatible with all conventional control systems. The pump is also fitted with a level input, can evaluate suction lines directly using a low level alarm and its large functional scope means that it can be deployed in a number of areas.Features & advantages: Capacity range up to 270 gph, up to 232 psig Power supply 115 / 230 V, ± 5 %, 50/60 Hz Material finishes PVC, PP, PVDF and stainless steel Stroke frequency manually settable via a potentiometer Release input for external start/stop Analogue input 0/4 – 20 mA Level input with a switching point Analogue output 0 – 20 mA Alarm relay output Stroke feedback output Double-diaphragm system (optional) CSA and UL certified MEMDOS LA 44-HP1010-HP2020-HP356080150 Delivery capacity at maximum backpressure (50/60Hz)gph 1.12.23.76.05.89.69.516.72441 Max. supply pressurepsig 14723217423217423214572 Max. stroke frequency (50/60 Hz)SPM 26721207212072120 Suction head for non-gassing mediafeet H2O 292623 Max. supply pressurepsi 7.3 Stroke lengthinch 0.3"0.4" Stroke volumeml/stroke 2.75.42.75.42.75.48.68.619.321.4 Nominal valve width DN4DN6DN10 Voltage supplyV 115 / 230 Motor efficiency Greate than 90% (energy Efficiency class IE4) Protection class IP55 Insulation class F Weight (without a motor)PVClb 2427 PP 2427 PVDF 2430 1.4571 2738 Max. ambient temperature°F 41 – 113 (104 with PVC parts) Max. temperature of the medium°F 176 (with PVC parts 95; with PP parts 140) MEMDOS LA 1101602102603104005107601010 Delivery capacity at maximum backpressure (50/60 Hz)gph 3038567078103133197270 Max. supply pressurepsig 1451181035844 Max. stroke frequency (50/60 Hz)SPM 9612096120961205376107 Suction head for non-gassing mediafeet H2O 2319143 Max. supply pressurepsi 7.3 Stroke lengthinch 0.4"0.5" Stroke volumeml/stroke 2.75.42.75.42.75.48.68.619.3 Nominal valve width DN10DN15DN25 Voltage supplyV 115/230 Motor efficiency Greater than 90% (energy Efficiency class IE4) Protection class IP55 Insulation class F WeightPVClb 43.445.65067.2 PP 43.445.65067.2 PVDF 44.146.751.571 Stainless steel (1.4571) 5564.575.8115 Max. ambient temperature°F 41 – 113 (104 with PVC parts) Max. temperature of the medium°F 176 (with PVC parts 95; with PP parts 140) Downloadshttps://www.lutzjescoamerica.com/fileadmin/data/dokumente/pg1/LJ-MEMDOS_LA-EN-BA.pdfhttps://www.lutzjescoamerica.com/fileadmin/data/data_usa/documents/pg1/Spec_Sheet-MEMDOS_LA.pdf
