The invention discloses a novel filtering piston pump which comprises a pump body (1). An oil inlet (2) and an oil outlet (3) are formed in the top of the pump body (1). An oil distribution disc (4) is arranged beside the oil inlet (2). A cylinder body (5) is arranged in the pump body (1) and is connected with a piston (6). A plunger (7) is arranged between the piston (6) and the pump body (1), and an exhaust fan (8) is arranged at the bottom of the pump body (1). A motor (9) is arranged beside the exhaust fan (8), and an oil spraying opening (10) is formed in the cylinder body (5). A filtering net (11) is arranged on the oil inlet (2) and the oil outlet (3). The novel filtering piston pump has the beneficial effects that design is reasonable, and the structure is simple; when the novel filtering piston pump works, most of pumps need to be configured according to anti-explosion requirements so as to reach the expected effect; and the novel filtering piston pump meets the requirements from the aspect of materials, strengthening composite materials are adopted, the novel filtering piston pump is strengthened, and the use safety is improved.
