Stringy and solid laden liquids wrap around and block an ordinary impeller. A torque flow vortex pump moves them a different way, with a recessed impeller set back out of the flow.
The impeller sets up a whirl, or vortex, that carries the liquid through the pump. Because the solids barely touch the impeller, they pass without wrapping or heavy wear.
This guide explains what a torque flow vortex pump does, where it fits, and how to keep it reliable.
What a Vortex Pump Does
In a vortex pump the impeller sits recessed, out of the main path of the liquid. Instead of pushing the liquid directly, it spins it into a whirl.
That whirl carries the liquid and its solids through the pump while they stay clear of the impeller. So stringy and gritty matter passes with little contact.
The trade is a little less efficiency for a great gain in the ability to pass difficult solids.
Where It Fits in the Plant
Liquids that carry fibre, rag, or stringy matter suit a vortex pump, since these would wrap an ordinary impeller.
Gritty and solid laden drainage also passes well, because the solids keep clear of the impeller as they go through.
By passing the difficult solids, the pump keeps these awkward duties moving without constant clearing.
Signs a Vortex Pump Needs Attention
A vortex pump in trouble shows up in flow and passage.
- Flow falling as the impeller wears
- Solids catching despite the recessed design
- Wear inside from gritty matter
- Leaks at the seal
- Vibration or noise while running
What Makes a Good Vortex Pump?
A vortex pump is judged by clean passage of solids and steady flow.
Clear Passage of Solids
The recessed impeller and open passage must let stringy and gritty solids through. Clear passage is the whole reason for the pump.
Hard Wearing Parts
Even with little contact, gritty matter wears the pump over time, so hard wearing parts help. They keep the pump passing solids for longer.
Keeping a Vortex Pump Running
Routine attention keeps a vortex pump passing your solids.
- Watch the flow for signs of a worn impeller
- Clear any solids that do catch
- Check wetted parts for wear
- Keep the seal and drive maintained
Common Questions About Torque Flow Vortex Pumps
Its impeller sits recessed out of the flow and spins the liquid into a whirl. The whirl carries the liquid and its solids through while they stay clear of the impeller.
Stringy, fibrous, and gritty solid laden liquids that would wrap or block an ordinary impeller. The solids pass with little contact in a vortex pump.
It is a little less efficient than a direct impeller pump, but it gains a great ability to pass difficult solids, which is worth it on the right duty.
Watching flow, clearing any solids that catch, checking wetted parts for wear, and maintaining the seal and drive keep it passing solids.
Pass the Stringy Stuff
A torque flow vortex pump carries stringy and solid laden liquids past a recessed impeller, so difficult solids pass without wrapping or heavy wear. That suits it to the plant awkward duties.
If stringy or gritty liquids keep blocking your pumps, a vortex pump is worth a look. Explore our pumps and plant equipment for the right fit.
