The two-staged or more tandem (or multiple) gear pumps are available as: STANDARD and T.C. (SHORT TANDEM). Standard Tandem. The suction of each single pump of the tandem is independent. Short Tandem (T.C.). Smaller dimensions than the standard type. The suctions of each pump are connected with each other. The T.C. (short tandem) requires a single tank. All “PS” gear pumps are machined for the tow of the next pump. Through simple assembling and disassembling operations, by using single pumps, it is possible to obtain the tandem unit. The limited quantity of the “connection kits and accessories” allows to reduce the stock value and supports a quick service.
