Areduce excessive cycling of the sanitary pump
Bprevent the sanitary pump from losing suction
Cprovide a higher pressure in the system than the pump can deliver
Dincrease water flow through the system
AI Explanation
The correct answer is A) reduce excessive cycling of the sanitary pump. A pneumatic pressure tank is installed in a sanitary system to provide a pressurized cushion that helps prevent the sanitary pump from rapidly cycling on and off. This helps extend the pump's lifespan and reduces wear and tear on the system. The tank acts as a buffer, absorbing pressure changes and smoothing out the pump's operation. The other options are incorrect because: B) preventing pump suction loss is not the primary purpose of the pressure tank, C) the tank does not provide higher pressure than the pump can deliver, and D) increasing water flow is not the main function of the pressure tank in a sanitary system.
