Suitability Verification For Effective Application/Use; Transport, Handling And Storage; Transport, Lifting And Handling; Storage Conditions - OBL X9 Series Operating Manual

X9 Series metering pumps
Consequently they are suitable for use in Zone 2/22, resulting classified in Group II Category 3 (No danger during normal
•
operation)
WARNING: The X9 pumps in ATEX execution are not suitable for use in zone 0/20 !
NOTE: In case of X9 pumps in ATEX execution, in addition to these instructions must be followed also the
warnings contained in "Metering pump safety instructions for potentially explosive atmospheres" (addendum to this
operating manual)

SUITABILITY VERIFICATION FOR EFFECTIVE APPLICATION/USE

All pumps are supplied in compliance with requirements established under technical/sales negotiation and defined at time of order.
NOTE: The customer (end user and/or installer) is responsible for checking whether or not the pump is really
suitable for the application/use on the plant, this before the installation and subsequent machine start-up.
For ATEX pumps the customer/end user is responsible to determine the effectiveness of the pump to be used in a
given plant, after having analysed the characteristics of danger existing in the installation location and in compliance with current laws
and those issued for safety purposes.

TRANSPORT, HANDLING AND STORAGE

4.1

TRANSPORT, LIFTING AND HANDLING

Unless otherwise agreed, the pumps are fixed and packaged in horizontal containers. Make sure that they cannot accidentally
tip over during transport or handling and that they are always place on a flat surface.
Verify that the device used (traspallets, forklift, hoist, etc...) is appropriate for the size and weight of the package/equipment and that
any lifting lugs on the machine are screwed down. In environments with temperatures below -20 °C, lifting rings must be used with
caution because they could break in low temperatures, causing damage to persons or equipment.
Lifting rings on the pump are sized to bear one-headed pump weight, therefore DO NOT use them to lift multi-
headed pumps. For those operations sling base-plate and use lifting ropes. Before removing ropes fix pumps safely to
the base. Pay attention, tilting danger !
4.2

STORAGE CONDITIONS

If not used immediately, the pumps should be stored with suitable covers in a temperate, dry, clean, vibration-free and weatherproof
environment. Protect from soil moisture by placing the unit on shelves or wooden pallets. If the temperature is below 0 °C, ensure that
it does not go lower than -20 °C.
If not specifically highlighted on the package, do not stack packaging, to prevent damage to the machine and to avoid tipping over or
falling that can create accidents. Ensure that access of unauthorised persons is not allowed in the storage location and that the floor or
shelf can support the weight of the machinery or equipment stored.
Before being put pumps into operation, after being stored for a long period, bring them to a temperate environment in order to stabilise
the temperature. In case of storage in extreme conditions, e.g. in sub-tropical or desert climates, take additional safety measures.
Particular storage conditions should be previously reported, in order to provide a suitable packaging.
4.3

DIMENSIONS AND WEIGHTS

Check the dimensions and overall gross weight of the package before handling or lifting.
Unless otherwise agreed, the packaging bears such information (dimensions are expressed in millimetres and weight in kilograms).

DESCRIPTION

The L series version X9 metering pumps are all with double diaphragm (sandwich) pumphead with rupture detector on the head
and fall into the family of controlled volume alternative displacement pumps.
The crank is driven by a constant speed electric motor (1500 rpm) and the number of diaphragm cycles is determined by the endless
screw – worm wheel internal reduction gear in an oil bath. The mechanically actuated replenishing hydraulic system ("intelligent"
diaphragm) makes the diaphragm immune from accidents or mishandling in discharge or suction.
