The Positive Displacement Pumps
are the most commonly used industrial pumps across a number of
industries. Roto Pumps is one of the top ten manufacturers and suppliers of
Positive Displacement Pumps in the world. Some of the most efficient PD pumps
manufactured by Roto Pumps are discussed here.
Progressive Cavity Pumps are quite common in several industries owing to the wide range
of applications they can cater to. These pumps can easily handle applications
involving liquids with both high and low viscosity, i.e. the thick consistency
between liquids and solids. Another feature that makes these kinds of pumps
suitable for a varied range of applications in terms of the rate of flow and
pulsation is that these pumps can be customized to suit the needs of the
individual projects. These pumps are also ideal for projects requiring large
pumping applications. Roto’s Progressive Cavity Pumps are provided with
small cavities, a double helix elastomer stator and a single external helix
rotor which help the pump to operate. The water passes through the cavities to
the discharge end of the pump once it is lifted through the suction end.
Another kind of efficient PD
Pump provided by Roto Pumps is a Helical Rotor Pump. These pumps consist
of a helical rotor and a helix rubber stator. The liquid is lifted inside the
pump with the movement of the rotor inside the stator. It keeps on lubricating
the rotor while moving on the surface of the stator. These pumps are very
sensitive in their operation and are capable of transporting the media without
affecting its quality or causing any wear and tear to the pump.
A High Pressure Slurry Pump
is also a kind of PD Pump that specializes in transporting unclean liquids with
solid waste elements. Their robust bodies deal with this kind of an abrasive
liquid efficiently. The parts of these pumps are also easily replaceable in
case of any wear and tear. This promotes the smooth functioning of the pumps
under all circumstances.
