How can I purchase Vacuum Pressure pumps 4EW DVVL please provide the specifications and also suggest me a best company deal in good quality vacuum pumps?
There are many companies available in a market, but people talk about quality products only, one company provide you good quality vacuum pressure pumps that is Falcon Vacuum Pumps & Systems.
Why are primary chilled water pumps smaller than secondary pumps?
PRIMARY CHILLED WATER PUMPS ARE SELECTED TO FULFILL THE REQUIREMENTS OF THE CHILLER WHERE AS SECONADRY CHILLED WATER PUMPS TO SUPPLY CHILLED WATER TO THE LOAD. FOR EXAMPLE TO THE FAN COIL UNITS & AIR HANDELING UNITS. IN NORMAL PRACTICE THE SECONDARY CHILLED WATER PUMPS ARE APPLIED WITH VARIABLE FREQUENCY (SPEED) DRIVE WHILE PRIMARY WITH CONSTANT SPEED, IN THIS ALSO PRIMARY CHILLED WATER PUMPS CAN BE USED WITH VFD SYSTEM.

What is use of centrifugal pump?
generally, centrifugal pumps are high discharge, low pressure generating pumps. to increase the pressure generated it is setup in stages wherein pressure increases from one stage to an other.mostly seen in daily life applications such as pumps for water tankers. even emergency fire fighter vehicles use these type of pumps. these are called dynamic or non-positive displacement pumps.
Which company deals in Oil free vacuum pressure pumps for paper folding machine with quality products and better services?
Falcon Vacuum Pumps & Systems is the best manufacturer and supplier of Oil free vacuum pressure pumps for paper folding machine in Mumbai and all over India. Falcon is known for its quality standard rules. One can rely on Falcon for the vacuum pressure pumps. Falcon feels proud to be number one in the customer satisfaction.
Where do you use reciprocating pumps in daily life or in industrial applications?
Daily life you use reciprocating pumps buy using your water faucet, pumping gas or simply using a suringe for medicine.
Do multistage centrifugal pumps have thrust balance?
Yes
What different between centrifugal pumps and multi pumps?
A centrifugal pump works by using centrifugal force. A multi pump is short for a multistage centrifugal pump with two or more impellers.
What is the difference between single stage and multi stage pump?
1、 single stage pump refers to only one impeller pump, highest head is only 125 meters; 2、 the multistage pump means to have two or more impeller pump, highest head can more than 125 meters; Multistage pumps in single stage pump head must match two levels motor cases, by adding more impeller number to equip with level 4 motor, which can improve pump using life and reduces the noise, but multistage pumps maintenance is relatively more difficult than single stage pump. 3、 pump actual required head is less than 125 m, can according to pump room area, pump prices (multistage pump price usually higher than single stage pump) factors comprehensive consideration to choose single stage pump or multistage pumps. With the development of technology, single stage impeller pump through improving the speed of the pump to improve pump head, can replace multistage pumps, just the price is more expensive.
Why non return valve is fitted on the suction side of the multistage Grundfos pumps?
I'm not famiar with the Grundfos valves specifically, but non-return valves are usually fitted to the suction side of pumps to prevent the pump from losing it's prime when it is stopped (by draining back through the inlet).
How do contractile vacuole help balance water?
By contracting rhythmically, this specialized vacuole pumps excess water out of the cell. That helps them maintain water balance.

Difference between single stage and multi stage centrifugal pump?
You should think of a multistage pump as a series of single stage pumps all mounted on one shaft with a single large case that holds all of them. As with all centrifugal pumps, the capacity of any single stage varies with the amount of head (discharge pressure) that stage develops. More head, less flow. Less head, more flow. In any case the single stage has a limited amount of head development at any given flow rate. To produce more head, multiple stages are operated in series so that each stage's head is added to that of the previous stage. Multistage pumps can be either horizontal or vertical in configuration.
What is mechanical balance?
Balance mechanical seal is a arrangement in centrifugal pumps that is provided to prevent leakage and corrosion of pump outer shaft. A cooling arrangement is also provided for mechanical seal.

When two centrifugal pumps are connected in series the discharge changes by factor of?
Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone.for two identical pumps in series the head will be twice the head of a single pump at the same flow rate - as indicated in point 2.With a constant flowrate the combined head moves from 1 to 2.Note! In practice the combined head and flow rate moves along the system curve to point 3.point 3 is where the system operates with both pumps runningpoint 1 is where the system operates with one pump runningSeries operation of single stage pumps is seldom encountered - more often multistage centrifugal pumps are used.http://nuclearpowertraining.tpub.com/h1012v3/css/h1012v3_76.htm
How many types of pump use in industries?
There are many types of pumps running in the market: Slurry pumps Chemical process pumps Sump Pumps Propeller Pumps Diaphragm Pumps Dredging pumps Submersible Slurry pumps Submersible Dredging pumps Submersible water pumps Piston Pumps Water pumps Vertical Axial Flow pumps Auto Priming Dewatering pumps Single screw pumps If you need more information, there is a brilliant resource available on the internet but I got most of my information from tftpumps.
