 Topic: Allis Chalmers Centrifugal Pump Questions
Posted: 02 Aug 2023 at 4:47pm |
I recently was given this Allis Chalmers Centrifugal pump. My friend bought a commercial building and this pump was sitting in the yard. I have no idea if this pump works or not, but I thought I'd take it and see if I can refurbish it and use it as a pasture irrigation system. My current pasture is on a very sandy soil. I have 10 Highland cattle and it would be great if this pump would work for irrigation. My pasture is next to a lake so I have a large supply of water for irrigation.
The pump has the following info on the plate: Serial #: 1-85133-1-1 Type: KSJF Size: 5x4 GPM: 500 Ft. HD: 139 RPM: 1760 IMP. DIA: 11.875
I'm kinda new to centrifugal pumps and irrigation so I have plenty to learn. I have a couple of questions for the guru's:
Would this pump be suitable for irrigation pasture?
The pump does not have an electric motor. Any idea what size motor this would need in order to drive it properly?
The pump has probably been sitting outside for quite awhile so I thought I'd take a look inside and see what may need to be cleaned/replaced. Any recommendations to this pump newbie would be greatly appreciated.

Problem might be in getting LIFT to the pump as it's made for moving fluid and not as a suction unit . So low input source but high head . A 5x4 pump depending on pressure needed would probably be minimum 20 HP to get volume - Or using a gas engine of automotive or tractor design to power it .
The bearing setup probably would not stand up to belt drive so direct couple to input would be needed . Split it and check impellers and case wear clearances , as it's a packed shaft the packing and wear ring in the gland would need replacing if no damage to shaft is present . I might have a wear sleeve over input shaft .
Most of the pumps I worked on were open face centrifugal pumps with impeller close to input opening casting .

How do you calculate HP from GPM and head?http://www.w3.org/2000/svg\" viewBox=\"0 0 24 24\"> "); display: inline-block; height: 24px; width: 24px; transform: rotateZ(-180deg);"> Formula: GPM * PSI / (1714 * efficiency) = HP.

those are tough old pumps that will work even when basically worn out.. Everything Coke said is good advice.....
you would need about 25- 30 HP minimum...( a little extra is better)... Most of those pumps will only LIFT water about 4 feet... Best to have the pump set at pond level to the inlet port.... 1 - 2 ft lift is great..
You can use this page to get the HP.... 139 ft is about 60 psi... ( 2.3 ft per psi).

to post photos, try to get the size at 800 x 600 pixels or less prior to uploading to the site... Most cameras are 5000 x 3000 or so...

I could put the pump near the shore of the lake where it would probably be a foot or two above the lake water level. Once the pump sucks in the water to the inlet, the pump would have to be able to push the water up an incline to the pasture that is somewhat steep. Don't know exactly the elevation, but my portable Honda gas pump has no problem pushing water up the hill.
I was hoping I could use something like a 5 HP motor for this pump. Don't think the electric company will like it if I using anything above a 5 HP motor. I'll have to check with them about it.

you would need a 3 phase motor of 30 HP to do it right.. That would be 480 volts.... not really a good option for ONE motor... You could use a small auto engine running at 1700 rpm.. but the gas price would have to be taken into account.
139 feet of head means the pump would PUSH the water up a 139 ft vertical hill ... or 60 psi.

Allis had a Fire Pump Division back in the day. That Division was sold off prior to the 1985 closure. I believe it is still in operation today.
