Effective and Competent Positive Displacement Pumps
by Sandeep Pandey BloggerRoto Pumps is among the top ten global
Positive Displacement Pump manufacturers. A Positive Displacement Pump is
designed to transfer an accurate amount of liquid over a defined period of time
while ensuring a precise volumetric rate of flow. These pumps are capable of
building high pressures. The flow of liquids usually depends upon the speed and
the discharge pressure during the pumping operations. But a Positive
Displacement Pump can manage to provide a uniform flow of liquid at varying
speeds and discharge pressures. These pumps can handle a variety of liquids
including highly corrosive and aggressive liquids.
Positive Displacement Pumps are named so as
they employ the principle of positive displacement in their working. A PD pump
operates with the help of two cavities at its suction and discharge ends. The
cavity on the suction end is expanding while it is shrinking on the discharge
end. The liquid moves inside the pump from the expanding to the shrinking
cavities after being lifted, and then is expelled from the pump. The pumps
operate as this entire process takes place in a continuous cycle. These kinds
of pumps cater to a number of industries including the food, chemicals and
petrochemical industries.
There are a variety of Positive
Displacement Pumps with varying features that help them in serving different
kinds of industries and applications.
One of such pumps is an External Gear Pump.
As its name suggests, an External Gear Pump comes with gears that are fixed
inside a casing. The pumps functions with the help of these gears as they move
inside the casing. The rotation of the gears in opposite directions from each
other lifts the liquid inside the pump, moves it through the intermeshing teeth
of the gears and then makes it exit the pump through its discharge end. As a type of a PD Pump, External Gear Pumps
are capable of creating high pressure during the pumping operations. Roto’s
External Gear Pumps are available in a range of materials and are used in oil
& gas and paint industries among others.
Roto Pumps is also one of the well-known
Chemical Dosing Pump manufacturers and suppliers. These kinds of Positive
Displacement Pumps are used for applications demanding accurate dosing. These
pumps operate with the help of a motor and a controller. The controller is an
important part of the machinery as it is responsible for controlling the rate of
flow of the liquid. These kinds of pumps are used widely used in several
industries including medical, food processing and mining.
The Chemical Dosing Pumps provided by Roto
Pumps are ideal for low flow applications as they can manage the minimum flow of
0.68 LPH.
