Vakuum-Empfänger
A standalone 120-gallon vertical carbon-steel receiver that adds evacuated buffer volume between a vacuum header and pump, with a full-vacuum/150 psi design boundary, dedicated gauge and safety connections, and a low-point manual drain.
- 120 US gallon vertical buffer volume
- Rated for full vacuum and 150 psi
- Dedicated gauge, safety and drain connections
Produkteinführung
The Vacuum Receiver is a standalone welded vessel for stabilizing an industrial vacuum header when process demand changes faster than the connected pump can respond. The selected purchasable basis is one Penway A7120-class 120 US gallon vertical receiver with carbon-steel shell and elliptical heads, neutral gray primer, threaded service openings and one circular base-ring support. Its evacuated volume absorbs short suction peaks and lengthens the interval between pump start/stop events, while the bottom head provides a defined low point for liquid that passes the upstream protection stage. The vessel creates no vacuum by itself: it is not the duplex pump-and-control station used for ID 1927, not the positive-pressure compressed-air receiver used for ID 1917 and not an atmospheric process-storage tank.
Key Features
Full-vacuum external-pressure design resists atmospheric collapse when the internal pressure approaches zero absolute
A 150 psi positive-pressure boundary gives the welded vessel a clearly defined two-direction design envelope
Elliptical welded heads distribute shell loads more smoothly than flat end plates and keep the vessel compact
One 3-inch-class main connection and one 2-inch-class secondary connection support a low-restriction header arrangement
Separate gauge and safety/vent couplings keep indication and protective accessories independent of the process connections
A bottom manual drain provides a controlled low point for liquid removal after the receiver is isolated and returned to atmospheric pressure
The continuous base ring spreads the vessel load around its circumference without projecting individual support legs into the service area
Kunden Produktbedenken
Receiver selection depends on usable evacuated volume, allowable pressure boundaries, pump control band, demand profile, line conductance, gas chemistry and the amount of liquid or solids that may reach the header.
A receiver selected only by nominal gallons may still be too small to absorb the peak flow between the high- and low-vacuum control pointsSize usable volume from the actual demand pulse, permitted pressure swing and pump response time, then verify the result against header conductance.
An ordinary thin-wall storage tank can buckle when exposed to full external atmospheric pressureUse a vessel with an explicit full-vacuum design boundary and keep the original nameplate and fabrication documentation traceable to the selected tank.
Condensate or cleaning liquid can collect in the bottom head and reduce usable volume or contaminate downstream serviceProvide upstream separation where carryover is expected, inspect the low point and drain only after isolation and return to atmospheric pressure.
Small nozzles, tight elbows or long branch runs can erase the response benefit of added receiver volumeKeep the main connection and header path short, size the line for the peak suction flow and avoid unnecessary restrictions near the receiver.
A corrosive or solvent-laden gas stream can attack carbon steel, primer and accessory elastomersReview the complete gas and condensate chemistry and select stainless construction, compatible coating and seal materials when carbon steel is unsuitable.
Poor foundation support or external pipe loads can distort nozzles and stress the welded shellSeat the base ring on a level load-bearing pad, anchor it evenly and support connected piping independently of the vessel nozzles.
