Technical Data Performance: m m m Capacity up to Head up to Speed up to   16bar (235psig)  Pump sizes 50-32-315, 65-40-315, 80-50-315 up to 25bar (363psig) Volute casing pumps for higher capacities, pump sizes up to DN 600 (24’’) and capacities up to 4600m3/h   (20250 USgpm) refer to design LS. Model LSB is a horizontal block pump based on hydraulics according to ISO 2858 / EN 22858 (from model LSN) with close coupled TEFC motor according to IEC design B 5. Standard IEC TEFC electric motors, design B 5 power range 2950rpm up to 37kW and 1450rpm up to 30kW protection IP 55, insulation class...

Cyclone Seal Chamber m The patented design of the cyclone seal chamber improves the life   time of the mechanical seal. Spiral grooves in the big conical seal chamber avoid contamination of sealing environment by solids. Enlarged clearance and big volume improve cooling and lubrication of the mechanical seal. The self venting design prevents the accummulation of gas (vapor) in the sealing environment. Seal chamber installation dimensions in accordance with ISO 3096 /   EN 12756    he correct seal selection is essential for the life time of the mechanical T seal. The flexible sealing system...

Simplyfies installation, lower installation costs. No alignment of pump unit required. Stub shaft made of Duplex (1.4462) and motor adapters for standard  IEC motors design B 5. Dimensions of block version reduced by 30% compared with frame mounted pumps. Ideal for OEMs or installation under space limited site conditions. Standard IEC TEFC motors Voltage / Frequency Insulation class F (temperature according to B) Standard motors for operation with frequency inverters and HYDROVAR.

Heavy Duty Casing Casted heavy duty, foot supported design provides maximum resistance against pipe loads Minimum 3mm corrosion allowance maximizes pump life Standard 3/8”-NPT casing drain for safe and simple maintenance ISO 2858 dimensions for easy installation in all systems and interchangeability Impeller Precision cast, enclosed impeller design for maximum performance and low NPSH Back vanes or balance holes reduce axial thrust and seal pressures for extended seal and motor life Key driven to secure maximum reliability Optional wear rings renew pump performance and extend pump life...
