Actually,
Screw Pump and Gear Pumps are Rotary Pumps.
Piston and Plunger are Reciprocating Pumps.
But all comes under the Positive Displacement type only.
Here the only main difference between them is except Plunger Pump all other types of pumps have their movable parts (Screws, Gears, Piston), that are necessary to increase pressure, inside their respective casings but for Plunger Pump, Plunger will be exposed to atmosphere.
Hence, it is the only one separate from the others.

Plunger pump has piston cylinder arrangement, hence reciprocating in nature while the rest of the pumps are rotary.
