Question

Which type of pump should be used to handle highly viscous fluid?

Answer 1

• Vane pumps usually operate at 1,000 rpm, but also run at 1,750 rpm.
• The pumps work well with low-viscosity liquids that easily fill the cavities and provide good suction characteristics
• Now reciprocating pumps typically pump highly viscous fluids like concrete and heavy oils, and serve in special applications that demand low flow rates against high resistance.
• Reciprocating hand pumps were widely used to pump water from wells.

Answer 2

$\huge\mathfrak\red{Answer</u><u>:</u><u>-</u><u>}$

Vane pump should be used to handle highly viscous fluid.

Justification:-

A Vane Pump is a type of positive displacement pump. It uses the back and forth motion of the rectangular shaped vanes inside slots to move fluids. They are sometimes also referred to as sliding vane pumps.

A slotted rotor is eccentrically supported inside a cycloidal cam. The rotor is located close to the wall of the cam such that a crescent-shaped cavity is formed. The rotor is sealed into the cam by two side plates. Vanes or blades fit within the slots of the impeller.
