split flow hydraulic pump supplier

ONE Dynex pump can supply multiple actuators, and synchronized movement can be achieved without flow dividers. Dynex pioneered this Split-Flow® technology over 60 years ago!

The checkball pump design uses individual piston check valves, offering a unique advantage among hydraulic pumps. Each pumping chamber can be isolated, and the output from each piston can be used separately.

Combination of VE43D/VP43D and overcenter valve OC Over-Center Valve (OC): The overcenter valve (counterbalance) is designed to control the movement of the cylinder subject to a negative load. This valve is suitable for double effect or oil return cylinders only. The overcenter valve permits a controlled lowering phase of the load avoiding danger for the operator and for the hydraulic system itself. The valve is set to factory values, no reguation needed by the operator. The unidirectional flow control valve (RFUA) is a cheaper alternative to the overcenter valve: in this case, the operator must shut the valve before the lifting phase, to gradually open it during the lowering phase to set the return’s speed. This is obviously a cheaper way to obtain speed control during the lowering phase but the operator is exposed to danger due to a less accurate management of the load. Assembled on a split flow pump, the overcenter valve allows a fine control on the lowering phase too.

For lifting and lowering applications on multiple points, Split-Flow Pumps are a far better alternative than using independently operated pumps. Where synchronization of maximum 4% is acceptable, SplitFlow Pump are a safe and economical solution.

Split-Flow Pumps are designed to move uneven loads uniformly during both lifting and lowering operations. Flow to each outlet is controlled via simultaneous operation of valves to provide even flow to each lift point regardless of differences in load. As long as all cylinders have the same load rating (effective area), the cylinders will move evenly based on this even output flow. For fine tuning at individual lift points, valves can be controlled individually. Advance / Hold / Retract functions provide complete control over multipoint lifts.

RHI is proud to represent Dynex and their checkball pump design, with its individual piston check valves. This design offers a unique advantage among hydraulic pump designs. With this design each pumping chamber can be isolated, and the output from each piston can be used separately!

This means ONE Dynex pump can supply multiple functions and synchronized movement without flow dividers. They call this Split-Flow® technology with it"s own patent.

The checkball pump design, with its individual piston check valves, offers a unique advantage among hydraulic pump designs. With our design each pumping chamber can be isolated, and the output from each piston can be used separately! This means ONE Dynex pump can supply multiple functions and synchronized movement without flow dividers. We call this Split-Flow® technology and we patented the design a long time ago.

Production of our official partner Dynex, the Split-Flow® pumps are pumps with several independent outlets suitable for supplying several consumers efficiently and managing the synchronisation of movements with greater flow divider precision.

New 3-piece construction allows for easy conversion from full-flow to multiple outlet configurations. Up to 10 independent flows are possible from this pump. The checkball pump design uses individual piston check valves, offering a unique advantage among hydraulic pumps. Each pumping chamber can be isolated, and the output from each piston can be used separately.

SFP-Series, Split-Flow Pumps ▼ SFP 421SW and SFP 404SW (pressure gauges and retract valves are not shown) Multiple Outlets with Equal Oil Flow Typical Split-Flow Pump Applications Split-Flow pumps distribute an equal amount of hydraulic oil to a maximum of 8 outlets. Smart valve technology allows both controlled lifting and lowering of heavy loads. Pressure compensated flow control This unique feature to our Split-Flow Pumps will ensure both smooth lifting and lowering. Independent of load distribution. • 2, 4, 6 or 8 split-flow outlets • Individual or simultaneous valve operation with advance/hold/retract function • Joystick (manual) controlled or pendant (solenoid) controlled valves • Flow per outlet ranging from 0,32 to 4,2 l/min at 700 bar • For double and single-acting cylinders • Pressure compensated flow control • Adjustable pressure relief valve per circuit • All models include pressure gauges • Reservoir: 20, 40 or 150 litres. ▼ During manufacturing of container units, the Enerpac SFP404SW Split-Flow Pump with 4 outlets provide both lifting and load distribution function. The container units weight between 70 and 120 ton and are complete equipped as full operational shelter for specific applications in power-gen, mining and construction industries for on-site use. For lifting applications Split-Flow Pumps are an efficient and safer alternative than using individual pumps. Where synchronization of maximum 4% is acceptable split-flow pumps are a safe and economical solution. Application examples: • • • • Bridge deck lifting for bearing maintenance Stage lifting in construction and shipbuilding Skidding to move structures and buildings Levelling of constructions like wind turbines. Remote Control Pendant Split Flow pumps with solenoid valves include a remote pendant with selector switches for each individual outlet, allowing single or multiple cylinder operation.

​The HSP series electric driven split flow hydraulic pump range offers users the opportunity to operate up to 8 independent hydraulic outlets from within a single pump assembly. With easy to operate controls HSP series pumps are ideally suited for synchronous lift applications particularly where there is uneven load distribution between the multiple jacking points. All models are 380/440 volt three phase electrical supply operation. Optional extra’s include a fully automatic PLC controlled synchronised lifting system, with a variety of user settings, such as target lifting height, maximum tolerance between the jacking points and other key settings, all controlled from a centralised touch screen computer.

HSP series pumps fitted with low voltage solenoid valves are complete with a low voltage control system, which allows the user to individually or simultaneously control each valve and the movement of the lifting cylinder pistons. Once the load is correctly supported, by the selected cylinder pistons, the synchronised lift operation can commence. The operation of the HSP Pump Unit can be entirely controlled from the remote control panel, which features individual valve on / off switches and a set of cylinder piston lift and lower buttons that can be individually selected for inclusion in the lift operation.

Enerpac model AM41 seven port split-flow valve enables control 2-4 single-acting cylinders simultaneously. All ports 3/8″-18 NPTF, maximum 10,000 PSI.

The Split Flow Pump has manual valves with joysticks or solenoid valves with a pendant to enable controlled movement of the load. The load can be lifted/lowered simultaneously using single or double-acting cylinders. Depending on the application, the lifting points can be operated individually or simultaneously.
