“Comet Cub” can refer to a diaphragm sprayer pump, not a complete centrifugal water-lifting set, so a business buyer must confirm the exact model and duty before comparing prices. By checking the pump’s flow, pressure, speed, accessories, application limits and delivered cost, you can decide whether to book a CUB unit or choose a different pump arrangement.
Key takeaways
- Confirm whether you need a CUB sprayer pump or water-transfer set.
- Match required flow, pressure and operating conditions before comparing prices.
- Compare the complete quotation, including power source, fittings, delivery and service.
- Request a testable specification and after-sales support terms before booking.
Confirm whether you need a CUB sprayer pump or a water-transfer set
Ask for the exact catalogue name before discussing price: is it a Comet CUB diaphragm sprayer pump, a complete CUB water-cooled pump set, or a separate centrifugal water-transfer set? A CUB is intended for pressurised spraying and some fertigation work; it is not automatically a replacement for an irrigation pump, high-head booster or tank-transfer pump.
Ask the supplier to confirm these points in writing:
- The exact CUB catalogue model and whether the offer is for the pump alone or a complete water-cooled engine set.
- The rated discharge in litres per minute, maximum pressure, pump speed and connection sizes at the stated engine, PTO or motor speed.
- Whether you need spraying, fertigation, tank transfer or irrigation, and which duty the quoted configuration is sized to perform.
- Every included item: engine, regulator, pressure gauge, suction and delivery hoses, filter, trolley, starter, fittings and couplings.
- Whether the price includes GST, transport, installation and commissioning.
- The water-transfer alternative if your requirement is filling or emptying tanks rather than feeding nozzles.
A reliable Comet CUB water pump dealer in Nagpur should explain nozzle sizing, pressure fluctuations, diaphragm and valve-kit availability, and seasonal repair support.
Ask a Comet water pump dealer for a model-specific datasheet, not a listing that says only “water pump”; that wording can conceal a mismatch between a sprayer pump and the duty you actually need.
Match flow, pressure and operating conditions to the job
Determine suitability by matching the Comet CUB’s rated litres per minute and pressure at your actual pump speed, not by choosing horsepower alone. Spraying requires enough pressure for the selected nozzles while retaining the required flow; fertigation requires compatible materials and sufficient flow against the injector’s resistance.
Tank transfer or irrigation demands a comparison with a centrifugal or high-head pump, because a diaphragm sprayer pump is not automatically a substitute.
Record these figures before requesting a quotation:
- Required application rate in litres per minute and total operating hours
- Nozzle pressure, boom or gun flow, and the regulator or bypass setting
- Total delivery head, pipe length, pipe diameter, bends, and elevation
- Suction lift, liquid temperature, liquid density, and chemical formulation
Check the CUB catalogue curve or test sheet at the intended PTO, engine or motor speed. A pump that reaches its maximum pressure only at a higher speed may deliver less flow in your setup.
Never run a positive-displacement diaphragm pump against a closed outlet; a working relief path, pressure regulator and bypass are essential, or hoses and fittings can fail.
Ask an agricultural water pump supplier in Nagpur to confirm diaphragm, valve and seal compatibility with your pesticide, fertiliser or cleaning chemical. Also test whether it can size the nozzle system, diagnose pressure fluctuation and supply genuine repair kits during the spraying season.
Compare the complete quotation, not just the Comet Cub pump price
Do not pay an advance until the supplier sends a pro-forma invoice for the complete Comet Cub water-cooled pump set, not a verbal comet cub pump price in nagpur.
The document must name the exact catalogue model, horsepower, pump size, engine or motor arrangement, rated speed and whether the quoted amount covers the complete set or only the engine.
| Quotation item | Confirm in writing | Why it changes the delivered price |
|---|---|---|
| Pump and power unit | Exact CUB model, 5 HP, 7.5 HP or 10 HP, and water-cooled engine details | A model name alone does not identify the configuration |
| Included equipment | Starter, regulator, trolley, suction and delivery pipes, filter, fittings and clamps | Missing accessories become separate purchases |
| Commercial charges | GST, freight to Nagpur, loading, installation and commissioning | A low showroom figure may exclude delivery |
| After-sales terms | Warranty duration and start date, service scope and genuine spare-parts availability | The warranty clock can begin before you use the pump |
The written Comet Cub pump booking must also state quotation validity, expected dispatch or collection date, advance amount, balance-payment trigger, cancellation and refund terms, and the documents required for invoicing. Ask whether the quoted delivery date begins after payment or after stock confirmation.
Give Nagpur Agricultural Equipment Engineers Pvt. Ltd. your application, required discharge, operating hours and power source so the quotation can be checked against the job rather than horsepower alone. Keep the invoice, payment receipt and final configuration sheet together; reject a booking that changes the model or accessories after payment.

Choose the right power arrangement and size for operating cost
A 5 HP configuration usually suits lighter spraying and shorter operating periods; 7.5 HP gives more reserve for pressure demand, longer hose runs and larger nozzle systems; 10 HP suits heavier commercial workloads.
Do not select by horsepower alone: a CUB diaphragm pump must deliver the required litres per minute and pressure at its rated pump speed.
| Option | Operating-cost advantage | Limitation or best use |
|---|---|---|
| 5 HP electric | Low energy cost where three-phase power is stable | Fixed location; unsuitable for remote fields or outages |
| 7.5 HP electric | Efficient for regular spraying from a reliable connection | Installation and cable capacity add cost |
| 10 HP electric | Handles higher duty without fuel storage | Higher connected load and demand charges |
| 5–10 HP petrol | Portable and quick to start | Petrol cost, noise and shorter refuelling intervals |
| Tractor PTO | Uses an existing tractor and suits field mobility | Tractor fuel and availability determine the real cost |
| 5–10 HP water-cooled diesel | Better endurance for remote commercial work | Fuel, servicing and engine downtime cost more |
| Other diesel pump set | Better choice for irrigation, lifting or transfer | A centrifugal set is not a direct CUB replacement |
Compare discharge at your actual total head, not at zero head. A CUB pump is for pressure application; choose a centrifugal set for bulk transfer or irrigation lifting.
Ask a comet water pump dealer to quote motor, engine or PTO drive separately, then include fuel or electricity, diaphragm and valve-kit replacement, spares and transport downtime. Treat the Comet Cub pump price in Nagpur as incomplete until the quotation identifies the exact model and complete power arrangement.
Demand a testable specification and protect uptime after delivery
A Comet CUB is not automatically a centrifugal irrigation pump. Before a Comet CUB pump booking, require the exact CUB catalogue code, not “Comet water pump” or a similar water-cooled diesel pump-set name.
Request these details in writing:
- Rated discharge at stated total heads, maximum pressure, suction and delivery connection sizes, allowable speed and suction lift
- Diaphragm material, oil specification, engine model, fuel consumption, fuel-tank capacity and water-cooled engine details
- Pro-forma invoice showing model, serial-number field, complete-set contents, GST, delivery date, warranty start date, installation scope and cancellation or refund terms
- Manufacturer catalogue, warranty conditions, operating manual, invoice and commissioning record
Use this acceptance comparison before signing the delivery note:
| Check | Pass condition | Reject or hold when |
|---|---|---|
| Model identity | Plate code and serial number match the invoice | Seller supplies only a generic “CUB” description |
| Mechanical setup | Correct rotation, oil level, suction filter and hose connections | Direction, oil sump or fittings are unclear |
| Water trial | No leaks, stable pressure and stated output with clean water | Pressure fluctuates or output is unverified |
Run clean water before adding pesticide or fertiliser. Ask the Agricultural water pump supplier in Nagpur for genuine diaphragm kits, valve kits, seals, oil, suction filters and hose clamps, with part numbers and lead times. A service contact who can diagnose pressure fluctuation during spraying season protects uptime better than showroom availability alone.
