Enerpac SFPKMN Master Network Control Panel for SFP Pumps

SFPKMN is the Enerpac master network control panel for SFP-series split-flow hydraulic pumps. It is the central controller of the SFP controller network kit: a touch-screen box in a transport case that lets one operator monitor and control a multi-point synchronised lift across up to four networked SFP pumps and adjust individual lift points as needed. Enerpac lists compatibility with the EVO and SFP pump series, and it is ordered separately, one per system of networked pumps.

One controller for a multi-pump synchronised lift

Large structures such as bridge decks, process vessels or ship blocks are lifted on many points at once. Each SFP pump is a split-flow unit with its own circuits; the SFPKMN ties up to four of them together so the operator selects pumps and cylinders on a screen and then holds the extend or retract key. According to the manual the SFP-Series electric split-flow pumps can achieve lifting accuracy of 4% across lifting points.

The manual is careful about one limit: the controller network box does not itself provide synchronised cylinder movement. The movement of each cylinder varies slightly with the flow reached and the load carried, so synchronisation still comes from the split-flow pump design.

Key features as printed in the datasheet

• Centralised control of multiple networked pumps with an industrial-grade touch screen and a user-friendly interface.
• Includes a transport and storage case; the controller should stay in the case and can be used with the lid open.
• Main screen selects the SFP and the individual cylinders, up to eight cylinders per pump, with motor status indicators.
• Key pad with system OK light, reset alarms, extend and retract buttons; emergency stop button on the panel.
• User screen sets several users with passwords and permission groups; a language screen sets the alarm language.

Technical specification

Product data (Enerpac page and instruction sheet L4475)

Kit components named in the manual

Selection and ordering guide

The SFPKMN is not a stand-alone pump. The manual states it must be used with at least one electric box SFPKSN and one communication cable SFPCOMM-25, and the network supports up to four SFPs. Plan one SFPKSN per pump, so a four-pump network needs four SFPKSN boxes.

The manual describes the kit for electric SFP pumps with a logo module and electric cabinet, and does not mention the diesel SFP-D units, so confirm the pump model first. The product page weight of 10 kg differs from the 13 kg printed for the controller case in the manual, so use the manual figure when planning transport.

Installation and operation notes

Installation steps from the manual: insert a micro SD card in each SFP logo module with power disconnected (any of the four cards can be used for any address); mount the SFPKSN on the upper part of the pump frame; move the pendant plug from the SFP to the SFPKSN; connect the CSFP cable to the SFP electric cabinet; and connect SFPCOMM-25 to the SFPKSN IN plug and to the SFPKMN communication plug. For several pumps, chain a second cable from OUT to IN and set the END OF LINE selector to NO, with YES on the last SFP.

To operate: release every safety stop, switch on the SFP main switch and the SFPKMN, log in, set the number of pumps and cylinders, select the SFP and cylinders, press the motor ON button on each electric cabinet, and hold the extend or retract key. The manual lists alarms such as motor off, communication failure, controller safety relay, emergency stop and 24 V DC protection with a cause and fix for each.

Applications in Oman and the GCC

Typical uses named by the manual for the SFP-Series are bridge deck lifting for bearing maintenance, machinery lifting and moving, skidding of structures and buildings, and shipbuilding. The manual warns that electric pumps must not be used in an explosive atmosphere.

Compatible accessories and related items

Named in the sources: SFP split-flow pumps (EVO and SFP series), the SFPKSN electric box, CSFP cable, SFPCOMM-25 cable, micro SD cards and the electric schemes ECSFPKSN, SFPCOMM-25 and SFPKMN. The manual advises against using the SFP series with multiple telescopic cylinders such as the RT and RLT series.

Frequently asked questions

What does the Enerpac SFPKMN do?

It is the master network control panel that lets one operator control up to four SFP split-flow pumps and select individual cylinders from a touch screen.

What else is needed with the SFPKMN?

At least one SFPKSN electric box and one SFPCOMM-25 communication cable, according to the manual; the pumps must be SFP or EVO series.

Does the controller synchronise cylinders?

No. The manual says the controller network box does not provide synchronised movement; the movement varies slightly with the flow and the load.

How many cylinders can be selected?

The main screen shows up to eight cylinders for each of up to four pumps.
