Reinforced shaft and bearing pedestal for long service life PFA/PTFE, PE-UHMW New: Highly permeation resistant PFA-P lining Richter Heavy-duty Chemical Process Pump

Richter SCK chemical process pump Fields of application Corrosive, pure and contaminated media in the chemical, pharmaceutical and petrochemical industries, in metal processing, waste disposal and recycling etc. • when stainless steel is not sufficiently resistant • alternatively to expensive Hastelloy, Monel, tantalum pumps • when anti-adhesive surfaces are important. The SCK is particularly economical and reliable with • less environmentally critical or hazardous media as pumps with single mechanical seals are lower priced than sealless pumps • high solids-laden, gas-containing or other...

SCK Very sturdy one-piece ductile cast iron bearing pedestal Standard feature: rolling bearings type 2RS with high load rating: • long-life grease lubrication, grease chambers outside on both sides to protect against corrosion • optional oil-bath lubrication • stainless steel labyrinth disc protects rolling bearings in case of mechanical seal leakage. © Thick-walled PFA/PTFE, PE-UHMW linings of the ductile cast iron housing • Armouring bears system pressure and pipe forces. No need for expansion joints • Virgin lining without fillers, full chemical suitability and optimum quality...

Frequently used mechanical seal versions The mechanical seal technology suitable for the SCK covers the entire range from reasonably priced, single-acting seals up to complex self-lubricated or externally lubricated and remotely monitored doubleacting sealing systems. Further information: See special publication „Mechanical seals for solidcontaining and crystallising media“ As a result, a mechanical seal pump can also be used in difficult operating conditions and for hazardous media. The most common versions are illustrated on these pages. Other versions and makes, thermosiphon and liquid...

SCK The pump housing with ductile cast iron armouring to EN-JS 1049/ASTM A395 absorbs all hydraulic and pipe forces to DIN/ ISO 5199/Europump 1979. In contrast to partially or non-armoured plastic pumps, no expansion joints are required. Flanges with service-minded through holes to ISO/DIN, ASME/ANSI, BS, JIS etc. Available on request: • housing drain, can also be used as a flushing and monitoring connection • heating jacket, e.g. for crystallising or polymerising media. Can also be retrofitted. Semi-open impeller with curved vanes The large metal core ensures the dimensional stability of...

Performance curves MNKA and MPB (up to 600 m3/h / 13 sizes from 25-25-100 to 150-125-315 are available for a pump 2,640 gpm and 140 m LC / 460 ft). design to suit your application. The curves relate to a viscosity of This range offers suitable pump 1 mm2/s. sizes both for applications in small production and test plants as well as for conveying large volume flows. Richter process pumps SCK are available for the performance range up to 300 m3/h (1,320 US gpm) and up to 90 m (300 ft) LC at 2,900 rpm. The SCK attains heads of up to 110 m (360 ft) LC at 3,500 rpm. Delivery heads which exceed...

Dimensions for frame-mounted and close-coupled pumps Conveyance of solids and gas-laden media With low solids contents it is frequently sufficient to merely install an internal or external liquid-sealed double mechanical seal with SSiC silicon carbide sliding surfaces. The vortex version SCK-X with an internal double mechanical seal RG-4 permits solids contents of up to 30 % by vol., in specific cases even up to 50 % and particle sizes of up to 10-20 mm (75-75”), depending on the pump size. The SCK-X is also ideally suited for media with long-fibre constituents and with gas contents of up...

Other Richter process pumps Richter magnetic drive and mechanical seal pumps are – just like Richter chemical shut-off and control valves – at home in a host of different chemical and related processes. This pump range also includes more specialised designs. The plant operator can thus choose from Richter pumps even for difficult applications. Close-coupled pumps as a space-saving alternative. 0.1 to 80 m3/h (0.4-350 US gpm) and up to 115 m (380 ft) LC at 2,900 and 3,500 rpm. Self-priming pumps for emptying containers and basins from the top. Suction height up to 6 m (20 ft) WC, suction...
