Rotary Trachodial Pump

Dev Engineers, a premier manufacturer and supplier of Rotary Trochoidal Pump in Ahmedabad, Delhi, Mumbai, Kolkata, Chennai, Bangalore, Indore, Ludhiana, Pune, and Coimbatore.

DESIGN FEATURES

In DIL series, there are only two pumping elements in latest internal gearing cum lobe principle. The flow of liquid is axial through the elements. This results in unmatched suction characteristics that are impossible in double helical pumps. Also there is only one shaft well supported at both ends of rotor for smooth, Silent, vibration-free running and eliminating bearing problems normally found in conventional gear pumps. Consequently, series DIL series pump has a very low noise level. This series needs practically no maintenance and has much longer service life than other types. This pumps are design for clear fuel Oils , Lubrication & Minerals Oils. The Pump Body is made from graded Cast Iron, Gears & rotors are made from sintered iron , shaft is made from En-Series Alloy Steel materials , Bushes are self lubricated sintered bronze , Shaft sealing is through NBR Oil Seal for leak proof working, In-built Pressure Relief Valve ensures safety against exceeds pressure and prevent electric motor from overload .

Above Pumps are also available in Closed Couple with Motor ie Mono-block version also to avoid misalignment of pumps & Motor, We can also supply L-type Right Angle Mounting bracket for Coupled design.

Advantages

  • 1. Single short shaft well supported by two self-lubricating bearings ensure high speed operation and vibration free running resulting in practically maintenance free pump with long service life.
  • 2. Unique pumping principle contributes to exceptionally high suction lifts and low noise level.
  • 3. Precision machined components guarantee high volumetric efficiency and overall efficiency
  • 4. Internal gearing principle with axial flow ensures pulsation free continuous flow.
  • 5. Compact and lightweight design eliminates elaborate foundations
  • 6. Single shaft design permits pump dismantling and without removing pump from base or disconnecting pipes. Pump can be serviced in place (Not possible in double helical gear pumps).

Applications

This DIL series of pump has been designed to handle fuel and lubricating oils as well as other fluids with similar properties. These pump are therefore ideally suited for following typical applications

  • Transfer of lubricating oils when emptying barrels and tanks
  • Pressure lubrication and cooling of bearings, oil circulation through cooler, gear lubrications etc.
  • Transfer of fuel oils to daily service tanks, preheating, circulation etc. lubrications etc.
  • Transfer of fuel oils to daily service tanks, preheating, circulation etc.
  • Boosting of fuel oil pressure for oil burner service and fuel injection pumps
  • Unidirectional flow design for reversing shaft duties as in machine tools, gear boxes and crane duties
