PRODUCTS | Pumps | Tandem-Double pumps

Design:
Tandem pump consists of two swash plate pumps of G1.614 series:
- 90 (or 71) + 90 (or 71) ccm/rev
- 124 (or 110) + 90 (or 71) ccm/rev
- 125 (or 110) + 125 (or 110) ccm/rev


Any combination of working displacements is possible: 28, 71, 90, 105, 110, 125 ccm/rev

Application:
The tandem pump is intended for operation in close loop hydraulic systems. Intended for application in hydraulic schemes of:
- rollers, vibratory compactors
- track-type vehicles: earthmovers, rovers, paddy harvesters
- wheeled vehicles: front loaders

Optima Hydraulics continues to widen the production. In the first quarter of 2012 on request of consumers, the following tandem pumps were developed and introduced into manufacture.

Tandem pump includes transmission swash plate pump G1.614 series and bent-axis pumps OPT.013, OPT.313, OPT.114 series.
Tandem pump is intended for application in road construction machinery, drilling rigs.
Tandem pump allows to exclude distributing gearbox and in some cases exclude belt drive of the pumps.
Owing to this the production cost is decreased while reliability is increased.
