Quick answer: A Filter Pump (water aspirator) creates vacuum suction using the Venturi effect from a stream of running water, making it a maintenance-free alternative to a mechanical vacuum pump for vacuum filtration. Filter Pump is priced at approximately ₹370 (indicative market benchmark, incl. GST, August 2026).
A filter pump, also called a water aspirator, generates vacuum suction using the Venturi effect: water flows rapidly through a narrow constriction, and the resulting pressure drop draws air in through a side port. Connected to a filter flask, this suction speeds up liquid-solid separation during filtration. Because it has no moving mechanical parts, it requires no maintenance or lubrication, and connects directly to a laboratory tap — a straightforward setup for vacuum filtration in college and research chemistry laboratories.

Frequently Asked Questions
How does a filter pump generate suction?
It uses the Venturi effect — water flowing through a narrow constriction creates a pressure drop that draws air in through a side port, generating vacuum suction.
Does this require electricity or a mechanical vacuum pump?
No — it’s water-driven and has no moving mechanical parts, connecting directly to a laboratory tap.
What connection fitting does this filter pump use?
The exact connection fitting and material have not been independently verified for this listing — confirm with STEMAids before ordering.
Is this suitable for a college chemistry teaching lab?
Yes — filter pumps of this kind are standard equipment for vacuum filtration setups common in chemistry coursework.
Does STEMAids supply matching filter flasks?
Contact STEMAids to confirm compatible filter flasks for a complete setup.
