Pump Control Panels (PCP / ShUN) — 0.4 kV, built to project

Purpose of the PCP

A pump control panel (PCP, Ukr. ШУН) is a 0.4 kV board that supplies and controls pump sets: booster and sewage pumping stations, drainage and fire pumps. Main circuits run at 380 V, 50 Hz; control circuits at ~220 V.

Panels for fire pumps are built to a separate technical specification, taking into account the requirements for fire protection systems.

Every panel is built for a specific project: the composition follows your automation design and the questionnaire.

What can be included — to project

• starting method: direct on line with a contactor, soft starting, or variable-frequency control;
• automatic transfer of the incoming supply;
• motor protection, voltage and phase-sequence monitoring;
• duty sequencing and rotation of the sets, operation by level or pressure;
• dry-run protection — from a liquid level control relay or a sensor signal;
• manual and automatic operating modes with a selector on the door;
• visual and audible signalling of operation and faults, signals passed to the supervisory system.

This is a list of options rather than a fixed configuration: what is actually fitted is set by the project and recorded in the questionnaire and in the circuit diagram supplied with the passport.

What we have built

We describe delivered work by its composition — by what is actually fitted inside the panels.

• Fire pumping station, 400 A: an incoming panel with automatic transfer, two starter panels with soft starting at 200 A / 110 kW and a third panel with direct starting — see the project case.
• Sewage pumping station, 160 A: an incoming panel with automatic transfer and two starter panels, one of them with a liquid level control relay.
• Control panel for four pumps, 2 A: "running", "fault" and "on" lamps, "start" and "stop" buttons for each pump, and four signal setting units.

LK Energy Group has been manufacturing switchgear equipment at its own factory in Odesa since 2015 (company since 2005). Every panel leaves the factory with a product passport and a circuit diagram; the acceptance test report is provided on request.

Composition of the panel

The constant part is the incoming device, the motor starting and protection devices and the ~220 V control circuits. Everything else is set by the project.

Incomer

a circuit breaker or a switch-disconnector with fuses — rated to the calculated current of the panel; to project, automatic transfer of the supply;

Starting

a contactor with a thermal relay, a soft starter or a frequency converter — to project;

Motor protection

motor protection circuit breakers, thermal relays, voltage and phase-sequence relays;

Control circuits

~220 V, with their own protective devices;

To project

liquid level control relays, time relays, mode selectors, lamps and buttons on the door, an audible and visual beacon, terminals for external signals.

Configuration examples from delivered work

• Fire pumping station, 400 A: incoming panel — two 400 A breakers (36 kA), a motor-driven load transfer switch of 400 A, an automatic transfer controller and two digital multimeters; two starter panels — a soft starter of 200 A / 110 kW, a 250 A switch-disconnector with fuses and a 90 kW contactor, one of them with a remote control keypad; the third panel — direct starting: a 160 A breaker, a 90 kW contactor, a thermal relay of 135–160 A and an audible and visual beacon.
• Sewage pumping station, 160 A: incoming panel — two 160 A breakers (36 kA), two 110 kW contactors and a voltage and phase-sequence relay; the first starter panel — a 55 kW contactor with a thermal relay of 88–105 A and three circuits of 2.2 kW; the second — two circuits of 55 kW, circuits of 30, 7.5 and 2.2 kW, a liquid level control relay and a beacon.
• Control panel for four pumps, 2 A: four signal setting units, lamps and buttons for each pump; enclosure 1000×650×300 mm, IP54, up to 40 kg.

The automation design is provided by the customer or their designer; we build the panel to it and issue the circuit diagram of the delivered version together with the product passport.

Main parameters of the PCP

The table shows the parameters of delivered work; for your project they are selected anew.

Final values are agreed at the questionnaire stage.

Scope of supply

• the pump control panel in accordance with the contract and the questionnaire — 1 pc.;
• product passport — 1 pc.;
• circuit diagram — 1 pc.

The acceptance test report is provided on request.

What is selected for the project

• the starting method for each set and the device ratings by motor current and power;
• automatic transfer of the incoming supply;
• the operating algorithm: duty sequencing, rotation, operation by level or pressure;
• controls on the door: mode selectors, buttons, lamps, metering and indication devices;
• signalling, interlocks and signals to the supervisory system;
• ingress protection, dimensions and enclosure colour — to order.

How to order

For a quotation send us the automation design or a list of the sets: the number of pumps, motor power, the starting method, the control method (level, pressure) and the installation site.

We quote the lead time together with the price, once the questionnaire is in: it depends on the set of devices and their availability.

Not intended for operation

• in environments with conductive dust, caustic vapours or gases that destroy metal and insulation;
• in places subject to heavy shaking, vibration or impact;
• on mobile installations.

Warranty

Warranty on the product — 2 years (extended to 5 years by agreement); the enclosure metalwork — 10 years*. The design service life to write-off is 25 years, provided that components with a shorter service life are replaced.

*Approximate terms and conditions. The exact warranty period is set in the supply contract.

A pump control panel (PCP) is a 0.4 kV board that supplies and controls pump sets: booster and sewage pumping stations, drainage and fire pumps; panels for fire pumps are built to a separate technical specification, taking into account the requirements for fire protection systems. Main circuits run at 380 V, 50 Hz and control circuits at ~220 V. The panel is built to project, and what exactly it carries — the starting method, automatic transfer of the supply, motor protection, operation by level or pressure, signalling — is set by your project and recorded in the questionnaire. In delivered work the rated current of the main circuits ran from 2 to 400 A, the ingress protection was IP31 and IP54, and the enclosures ranged from wall-mounted 400×400×350 mm at up to 15 kg to floor-standing 2000×800×800 mm with a 100 mm plinth at up to 200 kg. Starting was built direct with a contactor and soft with a 200 A / 110 kW unit; variable-frequency control is to project. LK Energy Group is a switchgear manufacturer from Odesa: the company has operated since 2005 and its own factory since 2015. Price on request.
