A dispensing pump implemented as modular functional unit comprises a piston body (10) having a piston section (11) and a cylinder body (20) having a cylinder section (21). The piston section (11) is slidably accommodated in the cylinder section (21). Both said elements define a pump chamber (30) together. An inlet channel (24) and an outlet channel (14) are connected via the pump chamber (30). A respective check valve (31, 32) is arranged in each of said channels (14, 24). Limiting devices (12, 22), which are adapted to be brought into engagement with one another, are provided on said piston body (10) and said cylinder body (20). In addition, a dispenser and a dispenser unit-assembly system are suggested.
