PROBLEM TO BE SOLVED: To provide a liquid sealed pump whose capacity per suction or discharge amount is reduced to reduce the liquid sealing capacity, and which has reduced driving power by preventing the movement of the front ends of blades apart from a liquid surface on the opposite side to the top. SOLUTION: The liquid sealed pump comprises an approximately cylindrical casing 20, an impeller 21 having the plurality of blades 21a eccentrically mounted therein, and a suction port 22 and a discharge port 23 provided in the sides of the impeller for sucking gas from the outside and for discharging part of the gas and liquid from the casing, respectively, wherein the liquid 24 sealed in the casing is rotated with the blades to generate liquid sealing cycles which sucks and compresses the gas with piston operation in a space formed between the blades of the impeller. The two liquid sealed pumps are arranged in parallel with their tops opposing each other, and the two casings are joined to each other at their overlapped portions being cut off.
