Rotary Gear Pump Type RDBX Rotary Gear Pump model RDNX Rotary Gear Pump in API versions
Handling high volume of viscous liquid at medium pressure is a challenge & calls for expertise.
The proven range of Rotodel rotary twin gear pump type 'RDRN' have been modified to achieve high pressure by reducing the bearing span, balancing the hydraulic force & blocking the slippage path but without compromising on the basic features prominent with all ROTODEL rotary pumps viz the compactness, efficiency, reliability & low noise level.
A pair of impeller with herringbone gear fitted on hardened & ground shaft with shaft sleeves in floating design supported on either side on needle/bush bearings located on end covers with ltb. wearing plate packed in between and placed inside close tolerance accurately machined casing with built in pressure relief valve makes the pump. Size 1/2" to 2 1/2" are provided with BSP thread inlet - oulet flange connections & they are available with foot or flange mounting. Size 3" to 6" are foot mounted with inlet-outlet port drilled to ASA-300 class. Type RDBX is a bush bearing version & is offered upto 2 1/2" size.
This pump can also be offered with different MOC viz. CI, CS, Bronze, SS etc. Pump upto 35 bar are also offered in this series by further reducing the bearing span. The flange type pump coupled with flange type electric motor is offered in horizontal as well as vertical construction.
Gear Pump Selection & uses
RDBX/NX series pump are medium pressure pumps designed for viscous pressure application up to 21 bar. The bush bearing version type RDBX is used for clean or dirty viscous & semi viscous liquid where the shaft surface speed is less. Pump upto 21/2" size can be run at 1440 RPM & for higher size the speed should be reduced to 960 RPM or lower. The self-lubricated needle roller bearing type can be used for clear viscous liquid & can be run at 1440 RPM for all the sizes. This pump are ideally suited for fuel pressuring, hydraulic, medium pressure lubrication & transfer applications.
All pumps are assembled after due inspection of each & every parts & than they are tested for duty parameters in accordance with API-676 & JIS-B 8312-1976.
