a gear pump is just that. it has a pair of gears in mesh with each other. a shaft drives one of the gears turning the other gear while oil is captured in the teeth outside the gears and carried from one side of the pump to the other.
a trochoid is similar in operation but uses an inner and outer ring to do the same thing. usually they are precision ground and orbit about each other. very similar to the internal workings of a wankel engine.
A major difference between lobe and gear pumps is that the rotors are designed to remain in close contact throughout rotation. By close contact, I mean that the lobes rotate about one another at extremely close tolerances. Also, unlike the gear pump, the rotors of the lobe pump do not mesh
one has external teeth the other has internal teeth
trochoid
both gear pump and reciprocating pumps are positive displacement pumps.but the different is gear pump rotary type.reciprocating pump moves liner motion.the piston moves up and down in straight line.
The "driving" or drive gear is the source of power or rotation. The driven gear is turned or moved by the drive gear. Example: The pulley on a motor is the drive pulley and a pulley on a pump is the driven pulley. Example: The pinion gear in a differential is the drive gear and the ring is the driven gear.

what is difference between inhibitor and antagonist
A gear type pump has two gears in it that pull fluid through between the teeth creating pressure as it is forced out the other side.

It should be running between the pump and the gear.
what is th different between end suction pump and singl stage pump and multistage pump
They may be the same thing.
