Pumps for plaster and mortar have to handle extremely abrasive substances. Sharp-edged quartzes and synthetic particles in plasters lead to high levels of wear. Yet pumps at construction sites have to meet high demands for operational availability. Their ability to do so is determined in large measure by the reliability and service life of their stators.
PFT rigorously test every batch of rotors and stators produced to ensure they meet their high quality standard, providing the end user with the end result of a high life expectancy in their rotor/stator meaning their money goes further.
