  • Page 9: Introduction

    The purpose of these instructions is to refer information deemed necessary for understanding as much as possible about and facilitating the installation, commissioning, use and maintenance of R series plunger metering pumps with a spring return mechanism, hereafter called, for short, R se- ries pumps.

  • Page 10: Regulatory Framework

    5 PRESENTATION R series plunger pumps are all with a spring return mechanism, coupled to a pump head in chemi- cally material (plastic or metal) that is compatible with the fluid to be dosed. The mechanism body incorporates a transmission reduction gear, a plunger thrust system and a flow rate adjustment sys- tem.

    5.3.1 OVERALL AND SECTIONAL DRAWINGS Given the importance of these documents (which can undergo further changes or updates), they are not considered part of this instructions manual. Unless otherwise agreed, they are therefore manually attached (latest edition). PERSONNEL RESPONSIBLE FOR MACHINE OPERATION Personnel must be professionally employed in the sector and suitably trained and must have read and understood the instructions in this manual.

  • Page 13: Technical Data

    GENERAL DATA 6.1.1 Noise The table below shows the average noise level (lp acoustic pressure) emitted by R series pumps, used within the limits of use and installed in accordance with the instructions in this manual. These average values were detected on the prototype at a distance of 1 metre from the surface of the machine, at a height of 1.6 meters from the service deck and weighted according to curve A.
  • Page 14 (1) Optional Powering the electric motor with an inverter The pumps must have been expressly ordered for powering via inverter. Otherwise, before their use, the user must contact OBL to define new limits of use (Hz, pressure and flow) that will be guaranteed only after new fitting of pump data plates.

  • Page 17: Storage Conditions

    The lifting rings on the pump are sized to withstand the weight of a single-head pump and therefore should not be used to lift multiple pumps. Sling the base with lifting ropes for those operations. Fasten the pump safely to the base before freeing it. Tipping hazard! STORAGE CONDITIONS If not used immediately, the pumps should be stored with suitable covers in a temperate, dry, clean, vibration-free and weatherproof environment.
  • Page 18 Protects the motor from overloading and/or electrical short circuits ATTENTION: R series plunger pumps are displacement pumps that always require a safety valve, installed externally on the discharge line (see "External safety valve") to protect against any excessive pressure.
  • Page 19 To facilitate dismantling of the pump from the system, provide for adequate drainage near the pump head on the discharge pipe. Provide for fitting nozzles to facilitate dismantling of flanged connections (see figure 4). Figure 3 Figure 4 After discharge connection of the pump, we recommend the use of a cross connection, both to fa- cilitate pump dismantling and to allow for (at a later time if necessary) installation of a pressure gauge, safety valve, pulsation dampener (dampener).

    NOTE: Always make the ground connection using the appropriate terminal in the terminal box. HOW TO CREATE SUCTION PIPES It is essential to set up the suction pipe properly to ensure proper pump operation.

  • Page 25: Discharge Pipe

    DISCHARGE PIPE Avoid setting up the discharge pipe or, worse, installing equipment directly above the pump. If the water surface of the suction tank is higher than that of the target tank, siphoning may be trig- gered (see figure 8). The fluid transfers spontaneously and uncontrolled from the suction tank to the target tank, going through the pump without it being able to control the flow rate in any way.

  • Page 26: Pulsation Dampener

    The external safety valve must be installed immediately after pump discharge connection and, in any case, before the SHUT-OFF valve (see figure 9). The exhaust must be visible, inspectable and aimed into a suction or drainage tank. Avoid connecting the discharge to the pump suction pipe (re- circulation), especially on small flow rate pumps.
  • Page 27 Due to its nature, the pump generates pressure peaks in the discharge pipe. In "closed circuit" dos- ing (example: in static mixers, press filters, other pressurised pipes), even if the process does not require constant flow/pressure, we suggest installing a pulsation dampener to absorb/reduce these peaks, to ensure correct dosing.
  • Page 28 BOTTLE DAMPENER: Fluids enters in the dampener and directly compresses the air inside it (without any means of separation). Dampener volume is approximately 35 times the pump displacement. Advantages: Less expensive compared to the bladder damper. Does not require pre- loading as it self-manages.
  • Page 29 Fluids enters in the dampener and compresses a pre-loaded separation bag or dia- phragm (distension chamber). Dampener volume is approximately 8 times the pump displacement. Advantages: More compact compared to the bottle dampener. Can be installed verti- cally or horizontally. Does not require periodic maintenance or need to be regenerated as the preloading gas always remains closed in the bladder.

Know and control actual pump operating pressure.

Clean the end of the shaft, lubricate it with oil and then proceed with aligning it without banging and with caution on the input shaft.

    During this first phase, check the actual operating pressure of the pump with a pressure gauge (see "Discharge pipe: Pressure gauge").

  • Page 40: Operation

    10.1 OPERATING PRINCIPLE R series plunger pumps are all with a spring return mechanism, coupled to a pump head in chemi- cally material (plastic or metal) that is compatible with the fluid to be dosed. The mechanism body incorporates a transmission reduction gear, a plunger thrust system and a flow rate adjustment sys- tem.

  • Page 41: Flow Rate

    10.2 FLOW RATE R series pump flow rate is not continuous but pulsating, generated by the alternating movement of the plunger and the action of the check valve on the head which determine flow direction (see fig- ure 1). Pump flow rate is adjustable and increases or decreases in direct proportion to the variation of the plunger stroke.

  • Page 42: Flow Rate Adjustment System

    10.2.1 Flow rate adjustment system Flow rate adjustment is continuous and regular and can be carried out both with the pump stopped and in movement. Activation with the pump running is, however, easier, especially for large diame- ter diaphragm pumps. 10.2.1.1 Manual adjustment with knob and linear vernier The standard model is provided when no particular adjustment system is specifically requested.

  • Page 47: Periodic Operations

    11.1.3 PERIODIC OPERATIONS As a general rule, after first start-up, close initial monitoring is recommended to practically define the maintenance plan and determine the frequency of general inspections and planned mainte- nance. If an abnormality occurs, it is the user's responsibility to consider whether to carry out maintenance earlier.

  • Page 48: Dismantling, Replacement And Reassembly

    Repaint whenever there is the need to protect exterior surfaces from corrosion. 11.1.3.8 Lubricating oil checks R series pumps are supplied complete with lubricating oil in the reduction gear (unless specifically requested) and ready for operation. Check daily that oil is at the halfway level of the cap and that there are no leaks from the dynamic seals or from the pump caps.

    Entrust maintenance, repairs and overhauls to experienced and qualified personnel who will restore original equipment conditions. Contact OBL customer support for information. 11.2.1 Disconnecting electrical connections Disconnect all electrical connections before dismantling the pump. Make sure the machine cannot be accidentally restarted. 11.3 CHECKING AND REGISTERING THE PLUNGER SEAL During periodic inspections, check for product leaks on the plunger seal.
