Tips & Advice to help you make your decision on Peristaltic Pumps

Peristaltic pumps are used for the timed transport of chemicals without risking exposure to contaminants. Liquid is forced through the tube by rollers which create pressure to generate a suction type effect which moves the materials from point A to point B. This is used for the distribution of chemicals often found in the medical field. Commonly they will be found in the moving of IV fluid. They are desirable for this task as the only component which interacts with the chemical is the tubing. The reduced number of factors involved makes it ideal for liquids which are at high risk of contamination.

The foremost concern when purchasing a roller pump is the materials that the tubing is constructed from. As it is the only variable affecting the liquid it must be made from a material which will not form a reaction when introduced to harsh chemicals. The next concern is the amount of pressure that may be applied to the tubing by the rollers. This determines the speed and accuracy with which the liquid will be dispersed.

Injection Pumps Key Terms

Injection pumps are one of the most important components of automotive engine systems. The performance of the engine greatly depends on the proper functioning of the fuel injection system. The fuel injection system determines the flow of fuel to the engine.

If you wish to establish yourself as an injection pump supplier or buy an injection pump, you will need to understand basic terminology associated with injection pumps. This guide covers some of the key terms related to injection pumps, such as a pump-nozzle injection pump, fuel injectors, fuel injection timing, fuel filters, actuators and insulating gaskets.

Pump-nozzle injection pump

A pump-nozzle injection pump is the latest pump technology developed for internal combustion engines. This is a high performance pump that removes the pressure lines that are associated with distributor injection pumps.

Positive displacement pump

Injection pumps are a type of positive displacement pump. Unlike centrifugal pumps, positive displacement pumps produce the same flow at a particular speed (RPM) irrespective of the discharge pressure.
Try: You can read through detailed technical information on positive displacement pumps and their types at The Engineering ToolBox, an online knowledge resource for engineering students and professionals.

RPM (Revolutions Per Minute)

RPM is a typical term related to the electric and electronic rotating devices. RPM is a measure of the rotational speed of a motor. It measures the revolutions that the spindle of a motor makes in one minute. The more revolutions per minute, the higher the power of the injection pump.

Fuel injection timing

Injection pumps inject fuel into the engine. Fuel injection timing controls the amount of fuel that the pump delivers to the engine by timing the opening and closing of valves in varied conditions without affecting the performance or the emissions of the engine.
Try: American Chemical Society offers a paper that provides information about the effects of fuel injection timing on fuel consumption, combustion and emission characteristics in diesel engines.

External gear pumps

External gear pumps are another type of injection pump. These pumps use two identical gears rotating against each other, out of which the prime mover drives the pinion and the other gear rotates with it. External gear pumps are useful for applications such as fuel systems and chemical industry equipment.
Try: Viking Pump Inc., a reputable manufacturer of pumps, offers information about various pumps, including external gear pumps.

Actuators

Pump actuators are the mechanical devices that activate the movement of the pump powered by electric signals. The actuators control the flow of fuel into the engine by controlling the movement of the valve to let the fuel in.
