DIAMOND SERIES With DN/DH Advantages www.novarotors.com

DIAMOND SERIES Nova Rotors presents its new range of progressing cavity pumps called the Diamond Series. Completely renewed mechanics to increase the performance with a new aggressive design. These pumps are completely reversible. Available a wide pumps range. SIZE 025 SIZE 030 SIZE 040 SIZE 060 SIZE 120 SIZE 300 • One stage stator with long pitch geometry to improve the performance. • Reversible flow up to 3 bar as standard: Up to 12 bar with hydraulic balance. • Pump fixed to motorization with a pin to permit the reversibility. • Joints: strong and compact with geometry and dimensions...

PUMP COMPONENTS ROTOR It’s a screw shape rotating into the stator, allows the pumping of the fluid. The pressure of the pump depends on the number of stages. Every stage gives a pressure of 6 bar. Nova Rotors has two types of rotors: standard and long peach geometry that, considering the same diameter and eccentricity, doubles the capacity increasing pump performance. MATERIALS: steel Aisi 420B, st.steel 304/316 and st.steel 304/316 HCP, hardened steel, ceramic steel, duplex. ROTOR STANDARD LONG PITCH GEOMETRY STATOR It is the fixed part of vulcanized rubber, contained or less on the metal...

GENERAL FEATURES OF THE "DN" SERIES The new "DN" pumps of the Diamond series can be used in a vast range of applications. Their most impressive features include high flexibility of use, standard construction, modularity and efficiency. The DIAMOND series boasts all those characteristics that make progressing cavity pumps indispensable in so many application sectors. These characteristics include: gentle, pulse-free pumping action accurate dosing pumping of high viscosity products, lubricant and abrasive, toxic and adhesive resistance to corrosive environments and to chemically aggressive...

Connection to the motor drive system is through a coupling flange and pin coupled to the shaft. This system is the most economical, versatile and reliable, as it minimizes manufacturing costs and times. The pin on the shaft has the added advantage of presenting the same resistance qualities in both rotating directions yet without reducing the space available for the seal system. The flanged coupling with oversized cross sections is unequalled in terms of compactness and ease of installation of the motor drive system. Standard the rotating parts are in stainless steel. The production...

The two sides of the stator are fitted with integrated seal systems which avoid the use of additional O rings, and also prevent the body and flange from rotating if the rotor and stator jam during pump start up. The rotors are manufactured with the utmost attention to finishing details and precision in order to achieve very low levels of roughness which maximizes pump efficiency by reducing the risk of jamming at start up. The rotors can be constructed from various materials and with different treatments and coatings to ensure the ideal solution for specific processing applications. The...
