90 m³/s 4 Outlet Capacity Pumping Station

ErichHahn HPDU is designed for the continuous pumping of heavy oil at operating temperatures not exceeding 200°C and viscosities between 20 and 1000 cSt.

Advantages of ErichHahn HPDU

Many different models of ErichHahn HPDU are available. Their designs and components are similar, but they differ in capacity, overall dimensions, and components.

Purpose of Use

The unit consists of a distributor with 3 or 4 outlets, a gear pump, a gear motor, a heavy oil filter, a control panel, an oil heating system, and thermal insulation. All equipment is compactly mounted on a frame.

3 or 4 Outlet Distributor
Distributes oil product flows to three or four outlets depending on the design of the unit.

The Automatic Process Control System (APCS) remotely controls the flow using electric actuator butterfly valves.

Gear Pump

The internal gear rotary pump is designed for the pumping of heavy oil.

The pump provides a continuous flow to reduce the vibration level and foaming of the pumped oil.

The pump has an integrated safety valve for protection against excessive pressure.

Heavy Oil Filter

The filter is designed to remove mechanical impurities from the pumped product. The operating temperature does not exceed 200°C.

The filter consists of a filter body, a removable cover, and a filter element.

Control Panel

The operation panel of the control panel contains controls and indicators related to the operation of the unit.

The control panel is connected to the central control panel for communication with the frequency converter.

The control of electric actuator gate valves can be used to start the pump and adjust the speed settings.

The basic operating parameters of the pump, the status of the gate valves, the presence of electrical network power, and the standby mode are provided as indicators.

Automation

The automation system of HPDU units uses remote I/O stations and is located in a heated and ventilated control panel (can be equipped with a PLC processor module if necessary).

It is used to control a frequency converter motor. Remote control is performed via a SCADA system or Profinet I/O (Modbus TCP/RTU if necessary) protocol.

Additionally, it can also be controlled directly from the control panel in local mode.

Heating and Insulation

The pump and filter are heated with a thermal oil heating system.

All units are covered with high-density thermal wool insulation and removable protective covers.

HPDU Gear Motor

The gear motor belonging to the manufacturer is designed to transmit and convert rotary motion to the gear pump via a flexible coupling.

The frequency converter in the power equipment cabinet is designed to start the pump unit and change its performance.
