	Characteristic Curves




	PERFORMANCE
	The constant rotation speed of the synchronous motor allows for a reduction of the pressure variations under varying load losses. Moreover, the CALPEDA pumps are not affected by the temperature and the voltage mains. The traditional pumps can do it only by using sophisticated and expensive electronics.	.
	RELIABILITY
	The motor never jams because: The patented "squared chamber" eliminates any possibility of rotor stoppage. The operational characteristics of the synchronous motor allow for a larger gap between rotor and rotor chamber, compared to what is possible in an asynchronous motor without reducing output. Being a permanent ceramic magnet, the rotor is less subject to limestone deposit than traditional metal rotors. The "intelligent" electronics can sense any rotation difficulties: in such circumstances the motor is turned over several times at a higher torque than in traditional motors. Always guaranteeing proper starting.
	CONSUMPTION
	Consumption cut out by over 40% With higher efficiency resulting in a lower absorbed current. This means lower consumption, guaranteed savings.
	SAFETY AND PRACTICALITY
	Reliable electronics guarantee the perfect operation of the electropump with double electrical insulation Class II motor for greatest safety for users. The reduced temperatures of the motor provide for the use of materials, which allow for an electropump with high electrical insulation, by eliminating the risk of dangerous electrical losses when compared to traditional pumps. Interchangeability The CALPEDA circulating pump has the same axis base of other traditional pumps. QUALITY/PRICE An extraordinarily advantageous quality/price ratio.
