I think I will agree with MintJulep and hydtools that the best is to simply clean the gap and leave it empty. I would think tar is too rigid. Thank you all for your suggestions.

I need to fill the 1" gap to isolate vibrations, reduce noise and protect the floor slab. This is an old installation, there used to some sort of elastomeric material in this gap, it has however dissapeared with the years and the gap is now full of dirt and debris. The contact material...

Hello, I am looking for a vibration damping compound to be used to fill a 1" gap between a concrete dynamometer base and the surrounding floor slab. Any ideas on a product for this application? Thank you,

Apparently Cycle Stop Valve is a brand name, is there a generic name for this type of valve or is this a patent protected sole source valve?

Thanks valvecrazy, With that low 1 GPM flowrate to the pressure tank, am I not going to have my transfer pump running almost constantly?

Thank you all for your comments, Itsmoked aswering your question, the storage and pressure tanks are pretty much level, being the latter seated maybe 3 ft higher. Valvecrazy, the cycle stop valve sounds good to me, and for my pumping capacity (around 30 gpm) not very expensive. Altough...

Hello, I have the following situtation regarding the installation of a water pressure tank and I would like some advice: I have a well with a submersible pump, pumping water to two 1000 gls storage tanks adjacent to the well site. About 1100 feet away from here there is going to be a...

I am working on the design of a Constant volume, DX a/c system (cooling only)for a Government Office. For the cooling load calculation I am including a ventilation load of 15 CFM/person in occupied office areas. Now in this same building I also have a cafeteria room, to be used only by...

Hello, I need to calculate the total demand of an LPG system of a building. Anybody has a link where the general procedure is explained. I have all the items requiring LPG (ovens, water heaters, dryers, washing machines) and their BTU/hr rate. LPG's calorific value which I understand is...

I see, so basically in the submersible the motor/pump are together in a housing and the whole thing goes inside the sump whereas in the wet-pit type motor and pump are separated. I would assume wet-pit tend to be used for higher capacities. Thank you!

Hello, can anyone explain me the difference between a wet-pit sump pump and a submersible sump pump. I have seen this difference established in an UFGS specs document but dont understand their difference. Thank you!

I am currently working on the design of a sawdust extraction system for a small industrial woodshop which must run underground. I am looking for ductwork suitable for this application. I have been recommended to use pvc-coated galvanized ductwork. However, I am concerned about the...

Hello, I am looking for guidelines/requirements for the ventilation of a lagging room. The room is small (17 x 13 ft.) and will be used for wrapping A/C ducts with insulation and working on fiber glass ducts. Is a duct collector required for this application, or can it be a simple...

Hello I am looking for a table comparing the Slurry Abrasion Response (SAR) test results (Procedure according to ASTM G75) for different steels. Any ideas where I can find this? Thanks,

Hello, I would like to know what is the max. recommended flow velocity for a 132" butterfly valve used as a water regulating valve in a dam. The water head is 125 feet. I have looked on the AWWA standards but they only cover valves up to 72". Thanks,

Hello, I am looking for master specifications or international regulations on Gamma ray shielding for Industrial Equipment. The Radioactive isotope is Cobalt 60 and the particular equipment is a radioactive concentration transmitter for a dredge. Thanks, A.

Thanks Jay, I actually meant gallons (of solution) per hour and this is pretty much a constant figure. Probably that is too much for a solenoid pump? Best Regards,

Hello, I need to select a metering pump for an Aluminum Sulfate Solution (20%) in a Potable Water Treatment Plant. Capacity: 100 gph, 24-hour full load service. What are the issues to consider when choosing between an Hydraulic and a Mechanical diaphragm pump? Advantages and...

Hi, I need information on seals for hydraulic cylinders working underwater. The application is the hydraulic drive of a couple of miter gates working in a lock. These cylinders worked above water level but now will be submerged aprox. 1 foot plus they will be exposed to pressure...
