surge alamo help

[jimsudz]

I just bought a surge alamo and want to know what model it is. The pump head is aprox. 5in. wide x 10in. dia. The inlet and outlet are both pointing up. The elecric motor is I believe a 1.65 hp surge motor (tag is unreadable)ther is an one peice oil reclaimer and a mosture/ equalizer tank. There are oil tubes going to each bearing. How much oil should I put in reclaimer? I want to wire it for 220 put the motor tag is whipped some of the wires ar labeled some are not any suggestions. Any idea on the amp. draw? Thanks

It sounds like you may have a Alamo 40 I think. I have a Surge Alamo that I was told is a Model 30. It is 4" wide.

The info I got on them is that they get wider for bigger models.

As for the Motor it sounds like the same as the one on my SP22.
It is a beast, weights about 50lbs. If memory serves me correct 115V 18A. Not sure about 220. I can check later.


I added a few pics of the motor that I have and it is also a 1.65HP

Dennis H. thanks for info actully the pump is 4 in. between end caps. I hooked up wires the way I think they were and it spins over but no vac. I took off reclaimer and dumped out little remaining oil ,it was very clean looking. The pump hasn't been used in 5 years the oil has leaked into the pump so I took off side cover and drained oil,I also fliped the vanes looks very good inside.After reassembly it has vacuum just need new belt a new rubber hose and some paint on belt guard. My motor looks a little newer than yours. I'll post a pic if I can figure out how. Thanks

I think I have the same pump. It measures 4.75 long including the end plates and the OA diameter is 10". I have a 240 motor I took off if anyone wants to buy it. WAs last used in a dairy this past spring.
I am now figuring how I need to adapt to mount an old 5hp snowblower engine. Should have it figured tomorrow. What is the desired rpm for the pump? I'm thinking I read about 400, is that right. I was thinking I would use a pully to hit the right rpm at about 3/4 throttle and put a stop to prevent over speeding. Then I'm thinking I'll try a slower engine unless more vac is needed. I will be using my ZERO vac tank so I will be using a vac regulator to hold it at 19" (I think 20 is max) If that doesn't blow my socks off I might use a releaser next year and go a few " higher vac.
What should the CFM of this pump be at the desired RPM at 19-20" vac?

I forgot a few things. This will be on about 550 taps with 2-3 sap ladders of about 5' and one of up to 10'. This will be on a wet dry system with 3/4" wet and 1" dry. The wet dry mainline will run out about 500' and then only 3/4" branch lines off the main.
I have all 30P 3/4" main and branch except one 600' run of black. I'm thinking about running 1" black for the dry, thinking the sap will only be in the dry line if the wet freezes so sap heating should not be an issue. Does anyone see a valid reason to run the 1", 500' dry line in 30P?

It sounds like you have a Alamo 30. Mine is also 4" wide not including end plates. The vanes measure about .010" under 4"
One thing to look at if you take a side cover off is that the vanes and rotor inside don't rub on the inside side covers when re assembled. Mine had shim stock, about .010" worth between the covers and pump body and when I took the thing apart they just fell apart, I didn't think I would need then but when put back together the pump would not rotate. So I had to get some sheets of .010" shim stock and make a new one.

If I get time I can post more pics of the rebuild I did to this pump.

One thing to look at is your pump rotation. Looking at the pulley it should rotate counter-clockwise.

[Dennis H.]

Checked the rpm on the pump.

The pulley on the motor is 4.5" and the pulley on the pump head is 10".
With a motor speed of 1725 that makes the pump ran at about 780 rpm's.

Thanks. I'll plan about that as max. Now I need to determin how I will get the sap out of the tank. Must I lose the vac or is there a way to keep vac while pumping. I will need to pump about 40-50' with no net lift. I need to lift about 6' but after that the drop to the road is almost back down the same. I'm thinking I will use a 1.5" pump. Still studying this.

If you spin it the wrong way the vanes wont spin out. Plus a little trick You can switch the plates and drum around if you need to to use a differant rotation motor. You just cant use the location pins:rolleyes:
