* Before starting the pump for the first time, it must be completely filled with working liquid as shown in figure below.
* Make sure the prime mover motor is isolated electrically and turn the pump-motor coupling by hand to check it is turning smoothly.
When pump is ready to be started, first briefly switch on and off the motor and check the direction of rotation is as per the marking on the pump.
* Start the pump and keep checking suction and discharge pressure gauges for rated pressure.
* Check prime mover motor ampere and compare with rated current.
Check for any leakages from mechanical seal or other joints of the pump, flanges, etc.
* Air in the pumping liquid causes abnormal vibration, noise and over heating of the pump and liquid which may result in a fire hazard.
* Periodically inspect foundation bolts, coupling pads, leakages and performance of the pump as condition monitoring to avoid breakdown maintenance.
All systems with screw pumps must be equipped with a pressure relief valve installed immediately adjacent to the pump.
* In normal medium capacity pumps, this pressure relief valve is an integral part of the pump to protect the system against excess pressure.
When liquid is circulated through the valve it heats up in proportion to the set pressure level and the percentage of by-passed liquid.

What is a Progressive Cavity Pump?
A Progressive Cavity Pump is a type of positive displacement pump, which consists of a rotor and stator. The metal rotor drives the stator through the chain and begins to fill the cavities with equal amounts of liquid which then get pushed through the pump outlet. They are a highly robust pumping system that ensure maximum performance and reliability.To get more news about screw pump stator, you can visit hw-screwpump.com official website.
How does a Progressive Cavity Pump work?
The rotor inside the pump rotates within the stator, as it turns, the cavities within the stator are filled with the process media and are carried towards the pump outlet under pressure. The pockets of fluid have a set volume that decides the volumetric flow rate of the pump, this is directly proportional to the rotational speed of the rotor and results in low levels of shearing and little to no pulse.
Are Progressive Cavity Pumps Self Priming?
Progressive cavity pumps do have the added benefit of self-priming capabilities. They cannot however run dry for very long. This is due to the rubber stator needing to be lubricated prior to liquid entering the pump. The Nova Rotas progressive cavity pump version has a suction lift of up to 8m and low NPSHa preventing cavitation occurring inside the pump.
Who are Nova Rotors?
Nova Rotas LogoTapflo UK is proud to have partnered with Nova Rotors SRL, a leading Italian manufacturer of Progressive Cavity Pumps. Founded in 1990 they are now a world-renowned and industry-leading force in the design, manufacture and production of Progressive Cavity Pumps & Wobble Pumps.
Tapflo UK supply Nova Rotor’s Diamond Series which was developed as a modular design to cover numerous models and sizes to meet the requirement for capacities up to 420 m3/hr and discharge pressures up to 48 Bar. The series can be customised to each customer’s requirement and can also be altered to meet changing applications within a business.
DN & JN Flanged Industrial Range
The DN and JN Flanged Industrial range is the basis for all ranges within the Diamond Series; DN covers all close-coupled pumps whilst JN covers all pumps in a long-coupled orientation through the use of a Plug-In Bearing Lantern Bracket. These ranges comply with API 676 requirements and are perfect for high-performance applications due to their reliable and robust design.
Hopper Pumps
Perfect for processing media with elevated viscosity and high solids content, where the DN/X, JN/X ranges might struggle.
