Q: How many types of chemical pumps are there?
  1. Diaphragm pumps: These pumps use a flexible diaphragm to displace the fluid through the system.

  2. Centrifugal pumps: These pumps use a rotating impeller to increase the velocity of the fluid, which is then directed to the system's outlet.

  3. Metering pumps: These pumps are designed to deliver precise and accurate amounts of fluid. They are often used in chemical processing applications where exact measurements are critical.

  4. Peristaltic pumps: These pumps use a flexible tubing to compress and move the fluid through the system. They are often used for dosing and metering applications in the chemical industry.

  5. Piston pumps: These pumps use a reciprocating piston to draw fluid into a chamber and then push it out through the system's outlet.

  6. Rotary pumps: These pumps use a rotating mechanism to move the fluid through the system. The most common type of rotary pump is the gear pump, which uses interlocking gears to move the fluid.
