Rotary  Stainless Steel Gear / Lobe Pumps

DGP-SS Series

rotary_external_gear_pumps_light_duty

The “ DEVPUMPS ” / “ DEV “  DGP-SS series external gear pumps are self priming bi-directional positive displacement rotary pump in all stainless steel ( SS-304 / SS-316 / SS-316 L ) construction with dry lubricating PTFE coated Self Lubricated or Carbon Graphite or PTFE Bush Bearings. These pumps are easy cleanable , easy maintainable in design without pressure relief valve. The right angle mounting brackets facilitates foot mounting of the pump on base plate with electric motor. The shaft sealing is by special PTFE Graphite Gland or Mechanical Seal for leak proof working with higher temperature range. Above SS Gear Pumps are also used as Metering / Dosing application with constant and continuous  flow.

 
  APPLICATION

STAINLESS STEEL ROTARY LOBE PUMPS
lobe_pump
lobe pump
 
  Design Features
SRL/ ALS / MSE  -Series Rotary Tri / Bi  Lobe Pumps are positive displacement ( pd ) external SS-316 Rotary Tri Lobe Pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing.  Unlike external gear pumps, however, the lobes do not make contact.  Lobe contact is prevented by external timing gears located in the gearbox.  Pump shaft support bearings are located in the gearbox, and since the bearings are out of the pumped liquid. As the lobes come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the lobes as they rotate. Liquid travels around the interior of the casing in the pockets between the lobes and the casing and it does not pass between the lobes. Finally, the meshing of the lobes forces liquid through the outlet port under pressure.
 
  APPLICATION

Lobe pumps are frequently used in food applications because they handle solids without damaging the product.  Ideal for pumping highly viscous liquids like Butters, Chocolates, Fruit Pulps, Flavorings, Frostings, Fats & Oil, Yeast Slurry, Sugar Syrups, Creams, Meat Chunk, Soup & Sauces, Tooth Paste, Resins, Jams, Jellies chocolate mixtures, Ice Cream, essential oil, shampoo , cheese, Face cream , Lotions, Baby Foods, tomato ketchup, fruit juice etc.
Capacity                       : up to 1,00,000 LPH
Head                             : up to 6.0 Kg/Cm2 pressure
Sizes                            : 1 “ to 3”
M.O.C                           : SS-316 Std.
