# 449-B    ALL BRASS   OPEN TOP   WINDMILL CYLINDERS

Open top well pumping cylinders are a great labor saver. Once you have installed the cylinder in the well, you can service the leather cups on the plunger assembly, without having to pull all of the steel pipe from the well. By removing the stuffing box from the top of the well, the rods can be pulled up and removed from the well, to get the plunger out of the well. After you change the leather cylinder cups, you can re-install the plunger in the bottom of the well, by putting all the rods back together as lowering them into the well. Cup leathers are available in several styles. We have soft brown 711 cup leathers, Graphite impregnated 707 leather cups, Hard 706 cup leathers and solid center leather cups too. We also stock neoprene rubber cylinder cups in several sizes which are full size and therefore do not need to swell up to the cylinder bore. The neoprene cylinder cups tend to be tighter and last 3 to 4 times as long as normal leather cups. When using leather cylinder cups, we recommend coating the outside of your leather cups with Vaseline to protect against swelling too much when put into the water. Uncoated leathers can swell up too much and become locked in the well cylinder bore, preventing them from moving, if not put into action right away.

Only 4 cylinders available at this Special Price.
 

The #449-B  all brass open top style cylinder allows for both the plunger assembly and the bottom check to be pulled for service without pulling the steel drop pipe. All are constructed of 13 gauge seamless brass tubing, with all brass caps, a 3 leather ball valve brass plunger, and a ball valve brass bottom check.
Most of the time you only need to change leathers on the plunger, since the job of the bottom check is to swell up the leather and lock itself in the bottom of the cylinder to keep water from going out of the bottom while pushing the plunger down.
Be sure to unscrew the bottom check from the plunger assembly prior to putting the bottom check in the cylinder. If you do not do this, the plunger will go up and down, but no water will be pumped, since the water comes in through the ball valve in the bottom check when your plunger is lifted, and when the plunger is pushed down, the bottom check seals and forces the water up past the ball valve in the plunger assembly. When left screwed together, water has no way to get above the leathers on the plunger.
 

# 442    ALL BRASS   FLUSH CAP   WINDMILL CYLINDERS

#442 All Brass, Flush Cap, Windmill Pumping Cylinders are smooth on the outside, not having exterior caps that take more clearance in the well. The inside has a bottom check, and a 2 leather plunger with poppet valve. These 2" thru 3" #442 cylinders use 7/16" steel rod for pumping. Unlike the cast iron brass lined cylinders, the brass cylinder wall is thinner than the cast iron shell on the A40 cast iron brass lined cylinders. When removing the cap to service the leather cups, be sure to place your wrench at the cap and top of the cylinder, and separate. DO NOT put the wrench in the middle of the brass barrel, or you may deform the cylinder, making it unusable.

The #442 cylinder is all brass and is made from seamless brass tubing. Its flush cap design (no outside caps) allows you to install a larger cylinder in a smaller diameter well. We have #442 all brass flush cap cylinders in 2", 2-1/4", 2-1/2" and 3" cylinder sizes tapped for 1-1/4" galvanized steel pipe and 7/16" steel pumping rod. We also stock 3" and 4" cylinders designed for installation with 2" galvanized steel pipe.
 

 

#442 ALL-BRASS SLIM-LINE CYLINDERS TO ENTER 2" SCH 40 PIPE

Windmill Catalog Page 61a

The two sizes of #442 All-Brass "Slim-Line" Cylinders are designed for entry into 2" wells. Many driven wells have less than straight shafts, and therefore may possibly hinder placement of a well pumping cylinder for your windmill or hand pump. Also Old Pipe tends to corrode over time and can cause problems putting a cylinder pump down the well. We offer both sizes that will go into 2" Sch 40 steel pipe, however we recommend that if your shaft is crooked or has a lot of corrosion, that you choose the 1 11/16" cylinder, since the extra 1/8" may be the difference between a successful installation or a hang up. These slim line cylinders are tapped for 1" galvanized steel pipe and 7/16" steel pumping rod.

A-40    CAST IRON   BRASS LINED   WINDMILL CYLINDERS

Many of you are familiar with the old cast iron, brass lined pumping cylinder. They are very durable, and last forever. The outside cap does stick out, making the well clearance more important. Because they are as rigid as they are, you don't have to worry about being wrench happy. You probably can not damage the cylinder.

N/A A403 3" x 10" Stroke x 16" Barrel Length Cast iron Brass Lined Pumping Cylinder for 1-1/4" Galvanized Steel Pipe   &   7/16" Steel Pumping Rod
 
 

These cylinders have a heavy cast iron body, a brass inside liner, a 2 leather all brass plunger, all brass bottom check poppet, 7/16" galvanized plunger rod, and heavy outside cast iron caps that are tapped for 1-1/4" pipe.
These Cast Iron Brass Lined Cylinders are designed for the guy who is wrench happy, since you can place your wrench anywhere on the barrel without the chance of deforming the barrel. The all brass pumping cylinders are more fragile, so you need to place your wrench near the cap to disassemble them. Never place your wrench in the middle of a all brass cylinder pump, since you may deform the barrel of the cylinder.

Cast iron brass lined cylinder is used with a windmill or hand pump to pump water.

Well pumping cylinders are stroke pumps. The cylinder has a plunger that travels up and down in the cylinder area, powered by the hand pump or the windmill. The plunger has leather cylinder cups that seal against the sides of the cylinder bore, and prevent the water from leaking back down while lifting. There is a check in the cylinder plunger. Many standard cylinders will have a poppet which drops down against the seat of the plunger to seal off and lift the water on the up stroke. When the plunger is pushed down, the poppet will lift up to allow water to pass through the plunger to the area above the plunger, making it ready to be lifted on the next up stroke.

Open top working barrel cylinders use a ball, instead of the poppet. The ball seals better and allow better flow of the water past the seat when being pushed down. The open top cylinder has a ball in the bottom check also. The #449B open top working barrel cylinders are great for deeper wells, since you can pull the plunger for servicing the cup leathers without having to pull the pipe out of the well.

Well pumping cylinders of either type use the principal of sucking water into the cylinder through the lower check valve on the up stroke, when the plunger is sealed off and lifting water to the surface. On the down stroke, the bottom check is closed and sealed, preventing water from going out the bottom of the cylinder. The plunger presses against the water trapped above the lower check valve, and causes it to push up through the poppet or ball in the plunger, to get above the top of the plunger assembly, so it is lifted up on the next up stroke.
