Installing A Vertical Pump Horizontall, is it possible? 1

[manhhoan]

Hello everybody,

I have purchased a vertical pump but because of the limitation of the height of the room the pump can't be installed vertically. Could anyone tell me that i can install the pump horizontally?

Thank you for help.

Depends, need more detail on the vertical pump configuration, manufacturer,model etc.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Usually the answer is no if you want it to last more than a few weeks / months or maybe even not work.

Everything on the pump would be designed with the direction of gravity fixed, hence the top bearing would be designed for vertical weight and not really horizontal forces. similarly the bottom bearing could be quite flimsy as in vertical mode it only has to hold the rotor in a horizontal position with no weight forces acting on it.

The rotor shaft may not be strong enough in horizontal mode not to bend or flex and hence vibrate a lot. The frame and support for the motor and pump will just be all wrong.

Whatever you do the vendor will promptly void any warranties or repairs if they find out the pump is horizontal when you specificed vertical.

sorry - time to order a new pump IMHO.

Verticals have been used for many years in horizontal or even angled configurations. As per above, tell the manufacturer what you want to do and get his opinion. One of the main concerns would be when the pump is NOT running. If left for a long time at idle, the shaft could sag and develop permanent deformation.
Hydroturbines (pumps by night and electricity generating turbines by day)were laid angled up the sides of hills with no ill effects at all. I personally studied the effects of these with Herman Gruetink (an old vertical master) solely trying to find any deleterious effects from angle install. None were found.

Generally, I would say this is fine, but give us the details to tear apart.
length, stages, column length, shaft diameters, distance between lineshaft bearings, etc.

Dubmac has it right.. "Could anyone tell me that I can install the pump horizontally?" - The only person who can do that with any authority is the vendor.

angle install is one thing, but completely horizontal is another.

How much more room do you need? Can you (or manufacturer's service person) take the pump apart and then install it? Can the length be reduced permanently (NPSH margins?)

Is the OP talking about a vertical multistage turbine pump????
Maybe yes maybe no - let's wait till we get more info.
