Pump selection tips
Hankia pump have the horizontal split case pump and vertical split case pump for your options. Usually the horizontal split case pump is prior to vertical split case pump because the horizontal split case is easier to install and maintenance as compared with veritcal split case pump.
For the same project, if both the end suction pump and split case pump can meet the service, split case pump usually need more budget although it has longer life time. So you can consider the split case pump as the secondary option if it is not critical project.Because of the unique feature of split case pump, the split case pump is usually preferred to the main pumps or critical projects.
DSP type axially split case double suction pump
DSP type is the axially split case pump, single stage, double suction pump that is completely designed according to API610 10th and ISO13709 standard. DSP split case pump is designed as the BB1 construction type. DSP type split case pump is mainly used for petroleum (oil), crude oil, chemical liquid transferring and loading on land or offshore.
However, Hankia Pump also can offer tailor made pumps to meet the special requirement on working temperature, corrosive liquid, NPSHr and efficiency, etc. in the projects. If you have special request for API610 / ISO13709 (BB1 type) split case pump, do not hesitate to contact Hankia, we will present to you an optimized proposal.
