Booster Pump

Why should an additional heat exchanger restrict oil flow, unless it is undersized?

If you increase the flow from the pump, will the rest of the hydraulic system be able to handle the increased flow?

A chain is only as strong as the weakest link.

There are ways to increase pump, but that may not be what you want.

Tell us more details, and the answers will be better.

Look at existing pump specs and see if it comes with a bigger impeller you can install

Additional capacity of your pump must be rated by introduced heat exchanger data.

If uprating the pump is the only way, then bear in mind that the electrical supply arrangements need to be considered too.

• Conductor sizes?
• Fuses?
• Overload?
• Upstream diversity arrangements?

A booster pump is mainly for increasing pressure.

If it is a centrifugal it may increase the flow but at a lower efficiency. It may also be better to reduce the impeller size to avoid overloading.

You would need the input from the supplier.

It is assumed that you have a positive displacement pump.

Note that you may have to increase the size of the motor as well. The power requirements will rise in proportion to the flow.

1) fit a new bigger pump unit. (first prize)

2) Increase the speed (if permissible).

3)

why my this post is going like guest and i am a member.

is it possible to increase speed

so that as per affinity law i can get same proportion of flow capacity and two times of head and i have to select three times of hp motor will it cause the increase in pressure (what will be the proportion).

is it good so that i can change only the motor with high speed and hp

i dont have details of heat exchanger. we fixed those in parellel not in series.

what if i put same spects of pumps on this different capacity of heat exchangers.will it affect to each other.

please advice me more
