45163836 - 24 V DC Diaphragm Pump Assembly LTC-IIS

45163836 – Diaphragm pump 24VDC LTC-IIS (Assy) – EFI VUTEk GS Series

The 45163836 diaphragm pump 24VDC LTC-IIS is the FRU (Field Replaceable Unit) in charge of the ink circulation in the supply circuit of EFI VUTEk GS Series large-format printers (also QS2/QS3 Pro and HS100 Pro).

Made by Parker Precision Fluidics, this miniature diaphragm pump of the LTC-IIS series integrates a 24VDC brushless motor and the patented Fluid-Block™ technology, whose double redundant seal removes any risk of ink leak to the electronic components. Its free flow of up to 1.5 L/min guarantees a continuous supply in intensive production. Designed as a field replaceable unit, it is installed directly by the technician and replaces the earlier reference 45087948. The 50 cm power cable is included in the assembly.
