Dekker Vacuum Systems

Our page highlights Titan liquid ring equipment, DuraVane rotary vane systems, HullVac rotary piston pumps, and Maxima-C large-capacity vacuum pumps. Compare each design against the pressure, flow, and process conditions required.

An impeller rotates within a casing containing seal liquid. The resulting liquid ring forms changing gas pockets that draw gas into the pump and discharge it at a higher pressure.

Seal liquid helps form the pumping chambers and carries away heat. Its temperature, composition, and circulation affect performance, so seal liquid conditions are part of the system design and operating checks.

A rotor with sliding vanes creates chambers that expand and contract as it turns. In an oil-sealed design, lubricant supports sealing and operation, and the exhaust arrangement manages oil carried out with the gas.

Consider it for a process whose gas or vapor load suits liquid ring technology. Review seal liquid compatibility, operating temperature, utilities, and exhaust treatment before deciding whether it is the right solution.

Some liquid ring configurations accommodate wet service, but allowable liquid load is limited by the design. Describe normal carryover and possible upset conditions so inlet separation and protective measures can be evaluated.

The seal liquid's vapor pressure changes with temperature and influences the achievable vacuum. Excess heat can reduce useful capacity, making adequate cooling and consistent liquid supply important to system performance.

Recirculation may be part of the system design. It requires consideration of heat removal, contamination buildup, liquid level, and makeup needs, so the arrangement should be selected for the actual process.

Specify the required absolute pressure and gas flow at operating conditions. Include evacuation time, vapor load, temperature, operating schedule, and utilities so selection covers both normal duty and anticipated changes.

Vacuum level describes pressure, while flow describes the amount of gas the system must remove. A pump must supply adequate capacity at the required pressure; either specification alone is insufficient.

Follow the model-specific manual. Depending on the design, service may involve lubricant, filters, seal liquid, cooling equipment, belts or couplings, and checks for leaks, abnormal temperatures, and changes in operating performance.

Leaks, inlet restrictions, excessive gas load, poor seal liquid conditions, or internal wear can reduce performance. Compare pressure and temperature readings with the original duty before selecting corrective work.

Review the gas composition, temperature, moisture, and possible lubricant carryover. Exhaust piping and any separation or treatment equipment must suit those conditions without creating excessive backpressure at the pump.

Possibly. Check available pump capacity, piping losses, controls, cooling, and utilities against the additional demand. Adding another user can change performance throughout a shared network, especially during simultaneous operation.

Send nameplate information, operating vacuum, process details, recent symptoms, and maintenance history. Photos of the pump, piping, and supporting equipment help explain the installation and identify relevant system constraints.
