DIAPHRAGM PUMPS AS POWER DRIVE](https://blog.comet-spa.com/hubfs/picchi%20di%20coppia%201.jpg)](https://blog.comet-spa.com/diaphragm-pumps/how-to-avoid-the-torque-peaks-in-the-sprayers-transmission) [Diaphragm pumps](https://www.comet-spa.com/agricultural/)are capable to act as power-transmission units. In particular, they can serve as a **drive of the fan** on the air-blast sprayers. In this application, the power is supplied by the tractor’s PTO and transferred to the fan via a series of multiple drives including the pump. Each element of the above chain drives the next one, thus generating **multiple inertias**, which require rather **significant torque** to overcome them, particularly during the start or stop stages. ![picchi di coppia 2](https://blog.comet-spa.com/hs-fs/hubfs/picchi%20di%20coppia%202.jpg?width=1200&name=picchi%20di%20coppia%202.jpg) No need to say that **Comet pumps are designed to stand torque peaks in any spraying condition**.  Nevertheless, **extreme overloads could arise in case of anomalies, i. e.:**   - **overspeed at the start** - **mechanical flooding** ![picchi di coppia 3](https://blog.comet-spa.com/hs-fs/hubfs/picchi%20di%20coppia%203.jpg?width=600&name=picchi%20di%20coppia%203.jpg) These events must be prevented by adopting appropriate measures, as they could cause severe damage. The best solution to overloads troubles is installing a **torque limiter** (e.g. a clutch) in between the drives. The t. l. **interrupts power transmission whenever torque exceeds the set value,** thus preventing peaks and consequent failures. **Comet Spa recommends torque limiters anytime there’s a proven risk of overload beyond** the limits\*. This will ensure maximum operational efficiency and reliability over time to your Comet pump. --- - *Please refer to Comet literature for power and torque requirements. High-efficiency torque limiters are available at manufacturers of premium-quality drive-shafts.* [![Scarica la Guida | Pompe a membrana: Installazione Diagnostica e Risoluzione dei Problemi](https://no-cache.hubspot.com/cta/default/5415755/3c6f8d3e-57b6-4279-a581-f4d6f977c7e8.png)](https://cta-redirect.hubspot.com/cta/redirect/5415755/3c6f8d3e-57b6-4279-a581-f4d6f977c7e8)     #### Share This Post!
