split flow hydraulic pump factory

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.

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.

Featuring 2, 4, or 6 split-flow outlets, SFP-Series suits multi-point lifting applications where synchronization of up to 4% is acceptable. Models offer individual or simultaneous operation of valves with advance, hold, and retract functionality. While values can be controlled manually via lever, remote pendant on models with solenoid valves allows single- or multi-cylinder operation. Each outlet provides 33–305 in.³/min flow at 10,000 psi, and reservoir capacity is 10 or 40 gal.

Menomonee Falls, WI — Enerpac introduces its SFP-Series Split Flow Pumps for lifting applications with multiple points. In comparison to using separately operated pumps, Enerpac split flow pumps provide a safe, economical solution for applications where synchronization of up to 4 percent is acceptable.

Featuring 2, 4 or 6 split-flow outlets, the SFP-Series offers individual or simultaneous operation of valves with advance, hold and retract functionality. The values can be controlled manually with a lever, or with remote pendant on models with solenoid valves. The remote pendant includes selector switches for each individual outlet, allowing for single or multiple cylinder operation.

“With multiple outlets providing equal oil flow, the SFP-Series Split Flow Pumps are optimal for lifting and pushing applications where even, safe loading is required,” said Peter Crisci, Global Business Development Leader for Enerpac. “Providing superior performance, our split flow pumps are ideal for lifting a bridge deck, repairing foundation, stage lifting of heavy transports or pushing tunnel segments.”

Each outlet provides flow ranging from 33-305 in3 per minute at 10,000 psi. The reservoir capacity is available in 10 or 40 gallons. The SFP-Series features a rigid protection frame with forklift pockets and lifting eyes.

To ensure optimal performance of split flow pumps, Enerpac gauges can be used to visualize pressure or load in the hydraulic system. Additionally, Enerpac offers a complete line of high-quality hydraulic hoses to ensure the integrity of users’ hydraulic system.

Enerpac is an international market leader in high-pressure hydraulics, with 28 offices in 22 different countries and over 1,000 employees. Enerpac produces thousands of high-pressure hydraulic products that are distributed worldwide. Enerpac focuses on the design of products, from the smallest cylinder to complete computer-operated lifting & positioning systems, which increase productivity and make work safer and easier to perform.

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.

Priority flow divider pumps split the flow between a priority port and an excess flow port. The flow is initially directed to the priority port until the priority setting is satisfied. At that time any additional flow is directed to the excess flow port. Priority divider pumps are typically used in steering circuits, brake circuits or any circuit where a primary flow needs to be satisfied first.
