Safety Chapter Safety information WARNING! Warning of hazardous feed chemical Should a dangerous feed chemical be used: it may escape from the hydraulic components when working on the pump, material failure or incorrect handling of the pump. – Take appropriate protective measures before working on the pump (e.g.
Page 11
The use of untested third party parts can result in per‐ sonnel injuries and material damage. – Only fit parts to metering pumps, which have been tested and recommended by ProMinent. CAUTION! Danger from incorrectly operated or inadequately main‐ tained pumps Danger can arise from a poorly accessible pump due to incorrect operation and poor maintenance.
The "Decontamination Declaration Form" can be found at www.prominent.com. WARNING! Slings can tear ProMinent only supplies “non-reusable slings” in accord‐ ance with DIN EN 60005. They can tear with repeated use. – Destroy and remove the slings as soon as the pump has been lifted into its final position.

Functional Description Functional Description 5.1 Pump The metering pump is an oscillating diaphragm pump, the stroke length of which can be adjusted. An electric motor drives the pump. The slide rod transmits the stoke motion to the diaphragms. Illustration of the stroke movement The stroke movement of the displacement body is continuously measured and regulated so that the stroke is executed according to a previously set „Metering“...
Functional Description With a suction optimised dosing profile, the suction stroke is elongated as much as possible, which makes possible a precise and problem-free dosing of viscous and gaseous media. Select this setting to minimise the NPSH value as well. P_SI_0104_SW 5.2 Liquid end The diaphragm (2) hermetically shuts off the pump volume of the dosing...
Functional Description The integral relief valve can only protect the motor and the gear, and then only against impermissible positive pressure that is caused by the metering pump itself. It cannot protect the system against positive pres‐ sure. The integral relief valve works as a bleed valve as soon as the rotary dial (3) is turned to "open": The valve opens and the liquid end can be bled.

Assembly Assembly Refer to the correct dimensional drawings on our web‐ site www.prominent.com for assistance. Compare the dimensions on the dimension sheet with those of the pump. Base WARNING! Danger of electric shock If water or other electrically conducting liquids penetrate into the drive housing, in any other manner than via the pump's suction connection, an electric shock may occur.

Assembly If the HMI is mounted remotely from the pump: a clearly marked Stop mechanism must be installed in the direct vicinity of the pump for emer‐ gencies! Discharge valve Dosing head Suction valve Ensure there is sufficient free space (f) around the dosing head as well as the suction and discharge valve so that maintenance and repair work can be carried out on these components.
Installation Installation CAUTION! Danger of injury to personnel and material damage The disregard of technical data during installation may lead to personal injuries or damage to property. – Observe the technical data- refer to chapter "Tech‐ nical Data" and, where applicable, the operating instructions of the accessories.

Installation Precise metering is only possible when the back – pressure is maintained above 1 bar at all times. If metering at atmospheric pressure, a back pres‐ – sure valve should be used to create a back pressure of approx. 1.5 bar. P_SI_0022 CAUTION! Fig.
Page 29
Installation CAUTION! Danger due to incorrect use of the integral relief valve The integral relief valve can only protect the motor and the gear, and then only against impermissible positive pressure that is caused by the metering pump itself. It cannot protect the system against positive pressure.
Installation When operating the integral relief valve close to the opening pressure, a minimal overflow into the overflow line can occur. Diaphragm rupture sensor CAUTION! Danger resulting from unnoticed diaphragm rupture If the pump has been ordered with an electric diaphragm rupture sensor, it still has to be installed.
– If the housing of the motor or electrical ancillaries has been damaged, you must disconnect it from the mains immediately. Only return the pump to service after an authorised repair. CAUTION! Use ProMinent cables to avoid unnecessary problems.

Installation If the pump is operated without the HMI, the supplied sealing cap must be plugged into the CAN port above the LEDs of the pump base. CAUTION! Risk of short circuit If liquid penetrates into the CAN port, a short circuit may occur in the pump.
Installation CAUTION! Pump can be damaged The pump can only be stopped when running via an: – External cable [Stop] key. – Use a relay or a contactor if the pump has to be defini‐ tively actuated via the mains cable. However, take into account the pump’s starting current.
