The required extension cord for the CTPMP Bazooka Continuous Flow Pump is a 12 gauge, 3-wire extension cord. The cord should not exceed 250’ (76 meters) in length. Please refer to the Operations Guide for additional information.
The BAZOOKA Continuous Flow system is designed to run one tool at a time. However, the system can fill standard automatic taping and finishing tools at the same time the pump is running a continuous flow tool.
No. The B89TT gooseneck is designed to fit the B74TT Bazooka pump without the need for gaskets or tools. This makes switching between the filler adapter and the gooseneck extremely fast compared to standard drywall compound pumps and saves money since you don’t need to purchase gaskets.
No. The TapeTech 76TT Loading Pump is designed with an integrated rubber gasket that eliminates the need for the old paper gasket. This feature saves you time and money!
If your TapeTech Loading Pump - 76TT, 72TT, 73TT, B74TT or B75TT - will not prime or pump the joint compound it is usually due to one of two possible causes. The first reason could be that the valve disc located just above the screen is blocked and cannot open to allow the joint compound to pass into the pump cylinder. The other reason is that debris or dried joint compound has collected in the foot valve screen and is blocking the flow of joint compound. The best way to fix this issue is to spray water directly into the screen/foot valve to loosen and remove any material. If pressured water is not available, try placing the loading pump into a bucket of clean water, and pump water through the pump until it will prime. Drain the water and place the loading pump back into the bucket of joint compound and then prime with joint compound. TapeTech offers a convenient maintenance kit, 501H1, to help you keep your loading pumps in the best working condition.
Generally, this leak occurs when the U-cup (part #700005) on the 76TT or 73TT pump is worn. The U-cup is a rubber seal that keeps the joint compound from leaking around the piston rod. To repair it, remove the brass gland and insert the U-cup. We recommend that that you insert a new bushing liner (#700029) at the same time as replacing the U-cup. TapeTech 501A is a convenient kit that contains all the necessary parts that you will need to make this repair.
If you are using either the TapeTech 76TT or the 73TT EasyClean Loading Pump, it is necessary to use a gasket (part #700049) to provide a good seal between the 90T Filler Adapter or the 85T Gooseneck and the Loading Pump head. It's a good idea to keep a supply of gaskets on hand to prevent downtime. If you use the B74TT or B75TT Loading Pumps, there is no gasket required. There is an integrated seal that prevents leaking. Additionally, these pumps include the filler adapter. The 76TT pump also has an integrated gasket and does not require a paper gasket.
It sounds like you’ve been doing a lot of work and the “O” Ring that is inside the 90T Filler Adapter is worn out. This “O” Ring holds the Filler Tube securely inside the Filler Adapter while you’re filling ATF tools with the 72TT loading pump. The good news is it’s easy to fix this issue! Simply remove the “O” Ring and replace it with a new one (part #709034). Be sure to thoroughly clean the area that this “O” ring is seated in to ensure proper installation.
The condition you describe, commonly known as "blisters", has two possible causes. First, when loading your taper with the loading pump and gooseneck, ensure that the bucket of joint compound has a sufficient amount of material for the loading pump to fill the taper and that you've properly primed the pump. Insufficient compound or improper priming can result in pockets of air in the compound that fills the automatic taper. While these air pockets won't damge the taper or effect its operation, it will leave sections of tape that have no joint compound behind them. Be sure to maintain enough joint compound in the bucket to keep the bottom of the pump covered and prime the pump to force out any air to avoid this problem. (Watch video) Another possible cause could be that you're not maintaining constant contact of the Taper drive wheels on the wallboard surface. Constant contact of the drive wheels to the wallboard is necessary to maintain a steady flow of joint compound onto the tape. (Watch video)
If you are using either the 72TT or 73TT pump, the fine mesh screen is part number 700032F and the coarse mesh screen is 700033F. If you own the B74TT Bazooka pump, the fine mesh screen is part number 740032 and the coarse mesh screen is 70033.
The B74TT BAZOOKA pump fills tools up to 40% faster than standard pumps through two features: an increased tube diameter allows more joint compound into the pump and the adjustable handle can be set to provide more leverage and increased “pull” with each stroke.
When filling the MudRunner®, we recommend that you first make sure that the filler nozzle on the tool is clear of any dry joint compound or other debris. Then firmly press the filler nozzle of the tool all the way into the filler adapter on the joint compound  loading pump. As you fill the tool, the joint compound forces the hydraulic cylinder down – be sure to hold the tool securely in the filler adapter or it may “push” itself off from the pressure. Make sure that your joint compound is mixed according to the manufacturer’s specifications. Add a small amount of water if the mix seems too thick or is difficult to pump into the MudRunner®. Finally, after cleaning the MudRunner® each time, lubricate the Rod Wiper with Ames Bazooka Oil. Proper cleaning and maintenance, along with this basic technique described above, will make filling your TapeTech MudRunner® easier.
