What is a chilled water pump?
There are two pumps the primary and the secondary pump. The primary is the chilled water pump which is what pumps cold water throughout the building and the secondary circulates the water.
How many fuel pumps do the 2005 Chevy Equinox have?
2 a primary and a secondary
What is secondary cold water system?
A secondary cold water system is a part of a building's cooling infrastructure that distributes chilled water from a central chiller to various cooling units, such as fan coil units or air handling units. This system typically operates at a lower pressure and temperature compared to the primary chilled water system, which generates and circulates the chilled water. The secondary system allows for greater flexibility in controlling temperatures in different areas of a building, enhancing overall energy efficiency and comfort. It often includes components like pumps, piping, and valves to facilitate the movement of chilled water.
Why does a Mercedes 300e has primary and secondary fuel pumps?
The Mercedes 300E features both primary and secondary fuel pumps to ensure reliable fuel delivery and maintain optimal engine performance. The primary pump is responsible for drawing fuel from the tank and delivering it to the engine, while the secondary pump provides additional pressure and flow, particularly during high-demand situations. This dual-pump system enhances fuel efficiency, ensures consistent performance, and helps prevent issues such as vapor lock or fuel starvation. Additionally, having two pumps can improve redundancy, increasing reliability in case one pump fails.
Where is the fuel filter located on a 1995 300E you have read of a primary and secondary filter Where are both located?
There is a filter screen on the outlet of the fuel tank. There is a filter mounted next to the fuel pumps under the car.
Why used of primary and secondary pump?
Primary and secondary pumps are used in systems like heating or cooling to enhance efficiency and reliability. The primary pump circulates fluid through the main system, ensuring consistent flow, while the secondary pump can manage additional loads or provide redundancy. This configuration allows for better control of temperature and pressure, improved energy efficiency, and the ability to maintain operation even if one pump fails. Together, they optimize system performance and extend equipment lifespan.
What is an example of primary activities?

How many fuel pumps does the 1988 Volvo 240 gl have and are they in or outside the tank?
The 1988 Volvo 240 GL has two fuel pumps: a primary pump located inside the fuel tank and a secondary pump located outside the tank. The in-tank pump is responsible for drawing fuel from the tank, while the external pump helps deliver it to the engine.
Procedure to switch on chiller plant?
If your chiller has the option of controlling the pumps then the start command should go to the chiller. The start command could be from a time clock or BAS. The chiller then starts condenser and cooler pumps then starts the compressor. It is important to allow the chiller to control the pumps to protect the tubes from freezing. The old way was often to turn on the chilled water pump then the chilled water flow switch would start the chiller. Check the installation, operation and or maintenance books for your specific machine, if you don't have them get them! many can be downloaded. Go with the manufactures recommended procedures to CYA!!
