What is an advantage of the Peri-jet eductor?
Peri-Jet eductors (2 ½ inch inlet and 4 inch outlet) are used in dewatering operations off the firemain to remove water and small debris from flooded spaces. Advantages of the Peri-Jet is the ability to pump small debris and hazardous fluids.
What is a Peri-jet eductor?
Description. Peri-Jet eductors are used in dewatering operations off the firemain or with a P-100 pump to remove water and small debris from flooded spaces. They are also used in engineering spaces to augment the main drainage system or other large compartments with significant flooding.
What are two types of Eductors?
There are two basic technologies for eductors which use compressed gas: exhausting and evacuating. Exhausting eductors remove the gas at a continuous rate while maintaining a stable pressure. These devices are often used to remove smoke from welding areas and to inject oxygen into liquid streams.

How does a eductor work?
How does an eductor work? Basically the eductor, often referred to as a Venturi pump, is a simple device that converts pressure to velocity when a fluid (liquid or gas) is forced through a restriction in an enclosed line. This creates a partial vacuum in the eductor immediately after the orifice.
What type of shoring is the strongest?
K” type shoring
“K” type shoring is at its strongest when the angles between the shores are 90 degrees or less. “K” type shoring is normally used when ships design and equipment configuration prevents “I” type shoring from being applied and the maximum length of the shore would be exceeded.
What is the proper sequence of activating an installed eductor?
What is the proper sequence of activating an installed educator? Discharge, fire main, suction.
What is the purpose of eductor?
What is meant by Eductor? Eductor is a simple type of pump which works on the ‘venturi effect’ to pump out air, gas or liquid from a specified area. Eductor require only a motive fluid or driving fluid for its operation, which allows it to use at any part of the ship including hazardous areas.
Why is eductor used?
An Eductor is a device that works on the venturi effect for pump operation. It is a type of jet pump used to pump out liquid/sediments where the suction head is too low for the normal pump to operate. Thus producing the pressure difference required for suction.
Which is better a peri jet or an eductor?
Peri-jet developed and manufactured exclusively by Derbyshire provides a method of pumping solid laden fluids far superior to the common Eductor. The Peri-jets (unique design allows larger solids to flow more efficiently without clogging.
How is a peri-jet used in dewatering operations?
Peri-Jet eductors (2 ½ inch inlet and 4 inch outlet) are used in dewatering operations off the firemain to remove water and small debris from flooded spaces. Advantages of the Peri-Jet is the ability to pump small debris and hazardous fluids. Disadvantages are its size, the size of the discharge hose and possible back flooding.
Why do we need Derbyshire Peri Jets and eductors?
Derbyshire also manufactures a wide range of common configuration educators. Our Peri-jets and Eductors are backed by proven performance data, which allows us to design your unit to meet or exceed your particular performance specifications.
