1. Applications they serve
2. The materials of construction
3. The liquid they handle
4. Their orientation in space

Types of Pumps:

General Choice
• Centrifugal
• Rotary
• Reciprocating

1 OH1 Foot mounted

2. OH2 Centerline mounted

3. OH3 (Inline flexibly coupled), OH4 (Inline Rigidly coupled), OH5 & OH6 (Inline closed coupled)

4. BB1 (Axial split 1 & 2 stage)

5. BB2 (Radial split 1 & 2 stage)

6. BB3 (Multistage axial split)

7. BB4 & 5 (Multistage radial split)

8. VS 4 & 5 (Sump Pump)

9. Reciprocating types can be Piston, Plunger or Diaphragm type

10. Rotary type can be Single rotor (vane, piston, flexible member, screw etc) or Multiple rotor type (gear, lobe, circumferential piston, or screw).

11. External and Internal Gear pumps
