Benefits Hot Water Pump Vleta 50-315
- Improved efficiency and NPSHreq by experimentally verified hydraulic design of impellers (vanes)
- Operating costs reduced by trimming the nominal impeller diameter to match the specified duty point
- Little wear, low vibration levels and excellent smooth running characteristics thanks to good suction performance and virtually cavitation-free operation across a wide operating range
- Casing sealed reliably – even in varying operating conditions – by confined casing gasket
- Extended selection chart with additional pump sizes for small flow rates
- Easy to dismantle due to back pull-out design; no need to remove the pump casing from the piping
- Easy to dismantle using forcing screws at the interface between casing cover and bearing bracket
- Optimum venting via the highly effective VenJet ® venting chamber
- Top reliability with double mechanical seal in tandem arrangement
- High resistance by anti-seize product-lubricated carbon plain bearing or SIC/SIC bearing

1
Impeller
Fully enclosed, single-piece casting gives reliability, long trouble-free operation and high efficiency.
2
Shaft
The shaft is protected by a replaceable shaft sleeve in stainless steel.
3
Bearings
Ample dimensioned single and double row ball bearings improve the stiffness and minimize shaft deflection.
4
Shaft bearing bracket
The heavy duty console with incorporated lantern assures silent and reliable operation.
5
Shaft sealing
SCP pumps can be fitted with most sealing arrangements:
-soft packing
-mechanical seal
6
Pump case
The pump case is of rigid design with a generous wall thickness, giving good protection against erosion and corrosion.
7
Wear rings
Front and back ( in case of impeller dia. >500mm) renewable wear rings are furnished in order to achieve the best pump performance and ease the maintenance.
