Type 1 in clean systems "WaG-Cer". Type 2 in systems that can tolerate some pressure drop "WAG-HO". Type 3 - they are much larger - for liquids that are not clean "WAG-MT". |

![]() For example ambient water is compressible by 0.05 ml per liter per bar. That is to say that you can pump 5 gallons into a full 100,000 gallon vessel simply by raising the pressure a bar - i.e. 15psi. Let us say your triplex mud pump produces 1/2 Gal per stroke per plunger, and that the divisor for a triplex is the square number of plungers - so 9, then the fluctuation will be 12.8 in3. Therefore a 554 gallon system, pipe volume plus bottle volume, will reduce pulses to 2 bar - i.e. 30 psi. So on slurry where we can not use the benefit of our 7° tubes, the compressibility is a vital figure for selecting a WaG/MT. |
