About Us
The simplified in and around flow design of UNIQUE Rotary pump permits easy handing of wide range of Viscosities and minimizes internal loss. Unique rotary pump is engineered for superior performance and longer life.
Long Life
Hardened Gears provide a longer gear life and quiet pulsation free flow. the helical configuration offers greatest face area for strength. Precision machined teeth engage gradually preventing trapping of liquid which absorbs shocks. Full hydraulic balance eliminates need for specialized balancing devices or thrust bearings.
Minimum Deflection
Bearings are internal, set close to the load. this short bearing span, combined with a short, stocky shaft, handles high pressure with minimum deflection. Force - feed lubrication by the pumped liquid results in less leakage and no contamination by the lubricant and eliminates the need for a separate lubrication system.

Note :
With higher viscosities pumps are operated at lower speeds.
General recommendations of speed are as under
| Viscosities Range In Cst | Pump Speed (RPM) |
|---|---|
| UP-400 | 1440 |
| 400 to 1000 | 960 |
| 1000 to 3500 | 720 |
| 3500 to 10000 | 500 |
| 10000 to 50000 | 200-300 |
| 50000 & above | Please Consult |
- This table is applicable generally for SAE-40 Oil
- Pump Capacity is directly proportional to speed
- If pumped fluid is poor lubricant, pump is operated at lower Speed, ranging from 200 to 1000 rpm depending on its property.
- Due to constant improvement in design, specification are Subject to change without notice.
Please consult our Application Engineer for selection of pump
Options
| Without Pressure Relief valve | Type UA |
| With Pressure Relief Valve | Type UAV. Protect system from discharge line obstruction |
| Mechanical Seal | Type UAM. Positive Sealing/ Minimum Leakage. Packed pump can be retrofitted. |
| Flange Mounted | Type UAF. Provide vertical mounting facility |
| External Bearing | Type UAX. It is an externally lubricated pump recommended for use where the liquid to be transferred does not contain any lubricating properties. |
| Stem jacketed Type | UASJ. Specially for liquids which solidify or become highly viscous at Room temperature like LSHS, FO, HFO, HHS, Glucose, Soap stock, high Viscosity Oils, Wax, Grease, Coal Tar, Bitumen, Adhesives etc. Steam circulating in the pump body to heat the liquid being pumped. |
| Higher Pressure | UAHP. By providing highly precision profile ground gear high pressure up to 70kg/cm can be developed. |
| Stainless Steel | UAS & UASS. For food product & liquid which react with CI & other maintenance |
| Custome Designed Pumps | To meet special requirements. |
Performance Curves Of Rotary Gear Pump
Pressure, Capacity & Efficiency Curve
Input B.H.P. pump, can be calulated by following formula
BHP (Rated) = Work Done
-----------
Constant x Efficiency
Q = Capacity in m3/hrx Pressure in kg/cm2

27 (Hydraulic Constant) x Efficiency
Relief valve Operation
Built in pressure relief valve is provided in pumps to operate at higher than rated pressure ie. it starts operationing 1 kg / cm higher than rated pressure and fully opens 20 % higher than rated pressure, taking maximum 30 % higher power than rated power.
