• There shall be a lifting eye on the end cap for removal.

• There shall be a fitting in the top endcap for water egress with a manual ball valve for shutting off overflow. (This ensures no air gap inside pressure vessel prior to pressurizing).

• There shall be a certified digital pressure gauge installed on the pressure vessel cap. The minimum specifications shall be as follows: 0-10,000 psi, +/- 0.02% accuracy, and an ISO/IEC 17025 accreditation.

2.2 Lifting Device

• There shall be a lifting device attached to the cart used in lifting and lowering the pressure vessel cap.

2.3 Pressure Vessel Bottle

• The internal diameter (ID) of the vessel shall be 10 inches.

• The inside working length (length after pressure vessel cap has been secured onto pressure vessel bottle) of the vessel shall be 34 inches.

• The pressure vessel bottle shall be properly mounted in the cart with even weight distribution.

• There shall be a 3/8” male pipe thread (MPT) hose fitting near the top of the pressure bottle on the backside away from the pump for water outflow from the pressure pump to the pressure vessel.

• There shall be a ball valve mounted to the bottle in line with the incoming water.

• There shall be a 3/8” MPT fitting in the bottom of the bottle for a water low point drain with a manual ball valve for shutting off flow. Coming off of the 3/8” MPT fitting there shall be a 36” flexible drain hose provided with the low point drain for draining into a bucket.
