Bypass pumping is
the pumping of sewage around a section of a sewer line in a pipe or channel specially constructed for that purpose

What is bypass pump?
Bypass systems are typically employed on a temporary basis. They
allow work to take place by pumping fluid
(sewage, trash, water, etc.,) around the construction or work area without stopping the normal flow of the fluid.
How does sewer bypass pumping work?
Most bypass work is accomplished using
centrifugal self-priming or centrifugal submersible pumps
. With a centrifugal pump, fluid enters the pump impeller along or near the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber, from where it exits.
What is a sewer bypass?
What is a Sewer Bypass? When sewers collapse or need repairs,
the flows must be bypassed
, leaving the damaged pipe clear to be replaced or relined. … Bypass pumping is a system of pumps, hoses and pipes that are used to divert the flow from a section of pipe being repaired, replaced or rehabilitated.

If a high pressure pump is deadheaded, significant damage results for the pump or the system. … Recirculation lines provide
a means of relief for high pressure pumps when operated against a closed valve or other system obstruction

What does taking off bypass mean?
Surgeons perform this type of surgery to bypass blockages in the coronary arteries. An “off-pump CABG” is a CABG performed without the use of a heart-lung machine (

.
What is a chilled water bypass?
What is the purpose of the chiller/heater system bypass? The purpose of the chiller/heater system bypass is
to prevent deadheading of the pumps when all of the internal unit valves go closed as well
as allow temperature and differential pressure sensors to sense active flow.
How do you bypass a control box on a well pump?
