LRP 1000 VSD+ 1950813008 Once-through with proportional valve (OT-PV), 3Ph 380/400/460 V 50/60 Hz

Atlas Copco LRP 1000 VSD+ – the top-of-the-range model with 37 kW

The LRP 1000 VSD+ reaches 1050 m³/h with dry air and 1140 m³/h with saturated air; the ultimate pressure is 25 mbar(a). The main motor delivers 37 kW. Dimensions 1950 × 810 × 1020 mm, dry weight of the standard version 900 kg, inlet and outlet flange DN 100 PN 10.

Designed for tough operating conditions

Liquid ring technology is suitable for wet, humid and dirty environments in which the pump is exposed to high temperatures, extreme vapour loads and even liquid and solid process residues. The “Automatic Seizure Prevention” algorithm prevents the pump from seizing after a prolonged period of inactivity. A control cabinet in IP54, mechanical seals, a lantern flange with automatic motor alignment and a removable heat exchanger make cleaning and maintenance easier.

Applications of the range

For the series, Atlas Copco lists food processing (cheese, milk evaporation, bottling, fruit processing, poultry and meat processing), plastics extrusion, rubber vulcanisation and forming, drying, sterilisation, evaporation, the forming of expanded polystyrene, filtration and transport.

Variants of the LRP 1000 VSD+

The LRP 1000 VSD+ is available from Ehrler & Beck in ten variants (part numbers 1950813005, 1950813008, 1950813011, 1950813014, 1950813017, 1950813020, 1950813023, 1950813026, 1950813032, 1950813035). They differ in the routing of the operating liquid, the material and the enclosure protection:

• Total recovery with plate heat exchanger (standard): closed system; the operating liquid is cooled and reused. According to Atlas Copco up to 95 % water savings compared with conventional once-through systems
• Shell-and-tube heat exchanger (TS): total recovery for poor water quality, more resistant to contamination
• Once-through with proportional valve (OT-PV): the operating liquid is discharged directly; the proportional valve matches its inflow to the process
• Once-through with centrifugal pump (OT/CP): variable-speed centrifugal pump for the seal water supply, without additional pressure from an external piping system
• Stainless steel (SS): all wetted metal parts made of stainless steel 316 for applications with chemicals or corrosive media
• Weather-resistant (WR): for (partial) outdoor use, housing with ventilation slots, electrical connections to IP56

Features of the LRP VSD+ range

• Plug and play: robust housing, controller, and inlet, outlet and main cable connections on the top
• Two VSD drives: vacuum setpoint control and controlled water circulation pump
• Automatic Seizure Prevention: protection against seizing after prolonged inactivity
• Acoustic enclosure
• MKV Elektronikon controller, compatible with HEX@GRID and the GENIUS platform
• Simple maintenance: IP54 control cabinet, mechanical seals, removable heat exchanger, access opening
