<h2>What are ULVAC vacuum pumps?</h2>
&nbsp;
ULVAC Inc. is a Japanese vacuum technology manufacturer offering a range of vacuum pumps spanning from oil-sealed rotary vane pumps for deep roughing vacuum to dry scroll pumps and high-vacuum turbomolecular pumps for ultra-high vacuum applications. In laboratory use, ULVAC rotary vane pumps such as the GLD series provide deep roughing vacuum in the 0.0001&ndash;0.1 mbar range, substantially below oil-free diaphragm pumps. These are used for lyophilizer rough vacuum, turbomolecular backing, and deep vacuum applications requiring high performance.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>
Two-stage chemical-duty diaphragm pumps delivering a steady 1.6 CFM flow rate with robust anti-corrosive materials to handle harsh laboratory vapors.
</li>
<li>
Oil-free diaphragm configurations designed to provide reliable, clean vacuum performance across routine filtration and evaporation workflows without risk of oil contamination.
</li>
<li>
High-capacity, fully chemical-resistant two-head diaphragm systems engineered to deliver a powerful 6 CFM flow rate for demanding industrial scale and high-volume processes.

<h2>How to choose an ULVAC vacuum pump</h2>
&nbsp;
Use rotary vane pumps for deep-vacuum roughing systems
ULVAC rotary vane pumps are used as roughing pumps in two-stage systems where a turbomolecular pump takes over after the system reaches ~0.01&ndash;0.1 mbar.
Consider oil requirements
Oil-sealed rotary vane pumps require regular oil changes and protection from solvent vapors using cold traps or molecular sieve traps to prevent contamination and extend pump life.
Consider dry scroll pumps for oil-free operation
ULVAC dry scroll pumps provide oil-free vacuum for applications requiring clean operation where oil contamination must be avoided.
Match pump capacity to instrument requirements
Pump selection should match required pumping speed and ultimate vacuum specified by high-vacuum instruments to ensure stable operation and reasonable evacuation time.
Consider noise, heat, and exhaust handling
Rotary vane pumps generate heat, noise, and oil vapor exhaust, which must be properly ventilated or routed through exhaust systems or fume hoods.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
ULVAC GLD series rotary vane pumps are widely used as roughing pumps in analytical instruments and vacuum coating systems, offering pumping speeds from a few liters per minute to tens of liters per minute with very deep ultimate vacuum performance. As of 2026, ULVAC remains a standard choice for mass spectrometry systems, electron microscopy, and high-vacuum laboratory applications.

Manufactured and imported directly from Japan, ULVAC DTC series diaphragm pumps feature integral forced-air cooling. They have two-stage PTFE diaphragms that are ideal for pumping corrosive gases and organic solvents. These pumps are oil-free, portable, and chemical-resistant, which means less maintenance and no more frequent and costly oil change, or cross contamination.\r\n\r\n
