The PLP Sanitary Lobe Pump is produced specifically for hygienic and sanitary applications within the food, chemical, and pharmaceutical industries. The series is fully compliant with EHEDG standards and has been designed with a heavy emphasis on achieving maximum performance & efficiency whilst offering compactness, robustness, cleanability & low maintenance costs thanks to its front pull-out design. The Lobe Pump range consists of 11 pump sizes, depending on the flow and solids passage requirements. Similarly to other pumps in Pomac’s range, the PLP Pump is entirely machined from cast Stainless Steel AISI 316L with a surface roughness of <0.8 as standard (<0.5 on request) to provide increased corrosion resistance.

Competitors’ units employ a cast iron gearbox with epoxy paint which can become eroded over time and need replacing/repairing. Pomac Pump’s Lobe Pump shafts are constructed from Duplex Stainless Steel 1.4462 to provide extra rigidity in operation. The pump can be fitted with several different sealing options and elastomer materials to suit almost any application.

With capacities up to 110 m³/hr and discharge pressures up to 15 Bar, this range of Sanitary Lobe Pumps is suitable for various applications. This, coupled with some key features and benefits, puts it apart from its competition as one of the most versatile Lobe Pumps on the market today. With the delivery of each product, the customer receives a lobe rotor tool and dummy rotors to facilitate easy removal and replacement of lobes and mechanical seals, further reducing downtime.

Traditional Construction VS Advanced PLP Construction

PLP Lobe Pump Traditional_VS_Advanced drawings

Traditional Construction Disadvantages

  • Long shaft overhang
  • Shaft deflection
  • Sensitive to temperature shock
  • No Front Pull Out construction
  • Not CIP approvable
  • Heavy construction

Advanced PLP Construction Advantages

  • Short shaft overhang – Less expansion of shaft due to high temperatures during CIP procedures.
  • Very low shaft deflection
  • Less sensitive to temperature shock
  • Complete stainless steel design – enhanced cleanliness
  • Modular design: All mechanical seal variants can be fitted to the same housing & pump can easily be switched from horizontal to vertical execution – all holes for mounting feet are pre-drilled.
  • Front Pull Out construction
  • CIP cleanable
  • “Lightweight” construction

  • Viscous & vulnerable Dairy products such as Yoghurt, Custard, Butter & Curdled Milk
  • Bakery products such as Dough, Fat, Paste, Fondant, Creams
  • Beverages such as Beer, Fruit Juice, Lemonade
  • Cosmetic products such as Creams, Shampoos etc…
  • Meat products such as Chopped Meat, Extracts, Animal Food
  • Egg products such as Albumen, Yolk
  • Viscous food products such as Sauces, Salads, Soups, Glucose Syrup, Chocolate
  • Starch products such as Mashed Potatoes
