Water Supply / Sanitation

Horizontal volute casing pump for high-volume hydrotransport of solids. For pumping slurries of large and very large particle sizes with a very good suction behaviour and high efficiency. Used in low-pressure applications. Pump components made of white cast iron.
Technical Data
• Max. flow rate30000 m3/h
• Max. head105 m
• Max. allowed working pressure15 bar
• Max. allowed fluid temperature120 °C

• Variable hydraulic system: the right impeller with optimum efficiency for every fluid. High operating reliability due to wide free passages.
• Double mechanical seal in tandem arrangement with fluid reservoir makes for high operating reliability.
• Low maintenance thanks to grease-packed rolling element bearings
• Standardised components are interchangeable within the Sewatec/Sewabloc and Amarex KRT series, so spare parts inventories can be optimised and costs reduced.

• The pump’s own weight ensures self-centring seating in the discharge tube, and an O-ring seals it; quick to install or remove.
• The slim motor minimises discharge tube flow losses.
• High reliability thanks to bearing temperature monitoring, vibration sensor, thermal motor protection, leakage sensors in the motor space and connection space as well as leakage monitoring of the mechanical seal system.
• Low-vibration hydraulic system; inlet ribs and optimised bellmouth for vortex-free inflow.

• Easy and fast installation/removal with polarised, absolutely watertight cable entry and KSB plug-type connection ensuring correct installation
• Motor absolutely watertight, also in the event of damage to the cable sheath and core insulation, with individually stripped, tinned and resin-sealed conductors
• High operating reliability with optimum motor selection for duty cycle S1, thermal class F, explosion-proof variant in "FM/CSA Explosionproof Class I, Division 1, Groups C & D, T4”
• Zero maintenance, ideal for continuous duty, with long-life bearings sealed on both sides, grease-packed for life

• Absolutely water-tight resin-sealed cable entries prevent any water from entering the motor – even in the event of a damaged cable.
• Reliable operation ensured by sensors monitoring the motor temperature and preventing overheating
• Non-clogging low-maintenance design with large free passages reduces clogging risk and, consequently, maintenance work.
• High-efficiency motors and variable hydraulic systems for optimum hydraulic efficiency and energy efficiency

• High efficiency thanks to enhanced power density (Wh/m3), overall efficiency of up to 69 %, lower total cost of ownership
• Non-clogging (no clogging by wet wipes) with patented deflection technology and D-max impeller
• Environmentally friendly with non-toxic, food-approved oil fill for lubricating the mechanical seal (liquid reservoir)
• Flexible thanks to easy substitution of competitor pumps with a large range of adapter claws and substitution pump app

• Safe and reliable operation ensured by control system (LevelControl Basic 1 / LevelControl Basic 2)
• Y-pipe simplifies planning and reduces installation time (included in the scope of supply of dual-pump units up to UZ300).
• Various positioning options and diameters make it easy to adapt the unit to the most complicated of site conditions.
• Collecting tank with optimum volume/footprint ratio for effective space utilisation
