What is the purpose of a wt30 pump?
The specially designed impeller allows solids to pass through easily, without clogging. Protects the pump, while offering a convenient tie down location for transport. The WT30 is designed for quick and easy service. An easy access service port makes clean-out quick.
Which is more efficient single volute or double volute pump casing?
At flow rates near the pump BEP, single volute casings are more efficient than double volute casings. Further, the inherent greater throat areas can also handle larger solids, as found in wastewater.
Are there any single volute pumps in the US?
Single volute pumps have been in existence for several years. With the exception of vertical pumps of the turbine type, the majority of single-stage pumps built in the United States are of the single volute type.
When does water come out the casing of a volute?
Once the point of greatest separation is reached – directly next to the cutwater moving in clockwise direction – the pressure is at its greatest, and water is forced out the casing when it encounters the cutwater. What a cutwater is to a volute, vanes are to a diffuser.

Which is more efficient a single volute or a double volute pump?
The hydraulic performance of double volute pumps is nearly as good as that of single volute pumps. Tests indicate that a double volute pump will be approximately one to one-and-a-half points less efficient at the BEP but will be approximately two points more efficient on either side of the BEP than with a comparable single volute pump.
When to use a double volute pump casing?
Double volutes are most common with larger-axial, split-case, double-suction impeller pumps, which also have lower-axial impeller loads. Double volute casings should not be used in smaller, low-flow pumps (below about 400 gpm).
Single volute pumps have been in existence for several years. With the exception of vertical pumps of the turbine type, the majority of single-stage pumps built in the United States are of the single volute type.
