SANITARY ROTARY LOBE
DESIGN FEATURES
• ADAPTABILITY
The modular design of this pump uses "bolt on" features which allow quick
and easy interchange of parts to enable exact specification of the pump
to suit any application… from stock!
• RUGGED DESIGN
The bearing frame design utilizes large shaft diameters mounted in high
specification taper roller bearings, fitted into rigid pillars which form an
integral part of the high grade alloy housing. These ensure maximum shaft
stiffness in order to avoid premature pump failure due to overpressure
or other abuse.
• LOW MAINTENANCE
The shaft, bearing, and gear assemblies are fully immersed in an oil
bath to give maximum life even at extremes of operating conditions.
The timing gears are easily accessible at the rear of the pump in the
unlikely event that re-timing should become necessary. Rotors are all
fully interchangeable making the need to re-time (which is a problem
associated with so many other rotary lobe and circumferential piston
pumps) virtually non-existent.
• IMPROVED HYGIENIC TECHNOLOGY
Fully swept pump chamber together with sealed rotor spline, accessible
seals, and approved sealing components ensure the pump meets the
stringent requirements ofmajor international customers. Nomodifications
necessary for CIP service.
OPTIONS
• SEALS
Single mechanical seals
are of hygienic design. Materials include carbon,
stainless steel, tungsten carbide, and silicon carbide.
Low pressure flushed seals
utilize the same single mechanical seal with
an additional housing. A low pressure flush liquid washes away crystallizing
products or liquids which 'skin over'.
Double mechanical seals
utilize all the components from single seals.
For hazardous, toxic, highly abrasive or sterile products.
Glandpacking
–acosteffectivegeneralpurposeseal fornon-hazardous liquids.
Used on either a stainless steel or hard chrome plated anti-wear sleeve.
O-ring seals
– another low cost seal option used primarily for self lubri-
cating products such as dairy products.
• ROTORS
Tri-lobe rotors
in stainless steel handle 90% of all applications. The tra-
ditional combination of efficiency, solids handling, low and high viscous
product capability.
Bi-lobe rotors
in stainless steel for exceptional handling of delicate, soft
solids such as fruit pieces and vegetables.
Rubber covered tri-lobe rotor
to cope with small hard solids such as
small bone fragments or ice crystals.
• CONNECTIONS
All US and European standards including DIN, SMS, RJT, IDF, Tri-Clamp,
ACME, NPT and BSP. Most pumps available with 2 different sizes, all fully
interchangeable.
• ELASTOMERS
Nitrile, Viton, EPDM, PTFE or Kalrez product contact joints are available.
