How mechanical seals work in pumps
Mechanical seals are extremely common in the pumping industry - and come in a wide range of materials and options. In this animation see how different mechanical seal types keep liquid from leaking ou...
What is a Gerotor Pump?
In this Pump Report, Chad describes a different kind of internal gear pump...the gerotor pump!
How an External Gear Pump Works (Multiple Gear Sets)
In this video, learn how external gear pumps - with multiple gear sets - create flow. Featured in this video is Viking Pump's GB-414 Series™. GB Series™ products are routinely used for high pressure a...
How Does a Gerotor Pump Work?
In this video we describe how gerotor pumps move liquid. Gerotor pumps are similar in operation to traditional internal gear pumps but swap the position of the drive and driven gears and do not use a ...
How Does a Gear Reducer Work?
In this video learn how a gear reducer - or speed reducer - creates a reduction in speed between the motor and the pump.
How it Works: Viking Circumferential Piston Pump
In this video, you'll learn what causes a circumferential piston pump to move liquid through a process.
How it Works: Viking Pump Vane Pump
In this video, you'll learn what causes a vane pump to move liquid through a process.
How it Works: Viking Pump External Gear Pump
In this video, you'll learn what causes an external gear pump to move liquid through a process.
How a Mag Drive Pump Works
In this video, learn how magnet driven pumps utilize magnets to rotate the pumping elements and create flow. Mag drive couplings can be found in a variety of pump technologies including internal gear,...
How it Works: Internal Relief Valve
This video demonstrates the operation of a pressure relief valve which is used to limit the pressure capability of a positive displacement pump.
Pump Report | Estimating Viscosity
In this Pump Report, Chad covers two simple methods for estimating your process liquid's viscosity.
How it Works: Viking Internal Gear Pump
In this video, you'll learn what causes an internal gear pump to move liquid through a process.
Running Internal Gear Pumps in Reverse
Internal gear pumps can be easily converted from one direction of rotation and flow to the other; or even be made to run in two directions of rotation and in two directions of flow. The capacity of th...
Pump Report | Relief Valves
Rotary positive displacement pumps are flow generating machines. With each revolution of the shaft, a fixed volume of liquid is moved from the inlet to the outlet. But what if the discharge line becom...
How it Works: Rotary Lobe Pump
In this video, you'll learn what causes a rotary lobe pump to move liquid through a process.
