Richter Vortex Type Chemical Process Pumps Higher solids contents Larger and fibrous particles Gas-laden media —:y Process Pumps & Valves

MNK-X, MNK-XB, SCK-X Conveyance of solids-containing and gas-laden media Vortex pumps are preferably used for media with higher solids contents. In addition, they have relatively good gas/liquid pumping capability. Media are conveyed gently for pump and medium • Solids contents of up to roughly 50 % by volume, depending on grain sizes and properties • Particle sizes of about 10 to 20 mm (2/5 – 4/5”), depending on the pump size • Long-fibre constituents • Gas contents of up to 5 % by volume Pressure/temperature range • Operating temperature: -60 to +180 °C (-75 to 360 °F), depending on design...

ቢ Pump housing • Ductile cast iron EN-JS 1049/ASTM A395 with thick lining made of PFA/ PTFE, PE-UHMW, PP • Connection for housing drain as standard • Highly permeationresistant and antistatic linings on request ባ Semi-open vortex impellers • Positioned outside the main flow • Radial vanes • Large metal core for increased stability • Secured against detachment in the event of start-up in the wrong direction of rotation • Back vanes reduce axial thrust forces Vortex pump MNK-X with magnetic drive, frame-mounted design (alternatively close-coupled design MNK-XB up to size 80-50-200). In the event...
