1. SPECIFICATIONS AND INSTALLATION

1.1 Operating Principle

The stators in F series pumps are "floating", that is they have one free end. This principle combined with flexible coupling simplifies the transmission of the movement of rotation between the drive and the rotor. The assembly is more compact than MOINEAU pumps in other series and allows the advantages of the progressive cavity technology to be applied at a low cost. The floating assembly of the stator has certain special advantages:

• Free expansion of the stator with variations in the operating temperature, without disturbing the operation of the pump.

• Exceptional silence through attenuation of vibrations. • Self-adjustment of rotor/stator tolerance through the action of the discharge

pressure on the external part of the stator. • Increased pump life span. • This type of construction makes it possible to build compact monobloc pumps.

Direction of Rotation (Warning - this pump is not reversible!) The pump's direction of rotation is marked on the top of the pump body. The pump is designed to be used in one direction of rotation only. It is the user's responsibility to check the rotating field of the electrical installation to ensure the pump rotates in the correct direction.

To use

Return to tank or to drain

1.3 Equipment Installation All MOINEAU pumps are lubricated and tested in our workshops before being dispatched.

1.3.1 Installation Precautions The pump must be secured to a horizontal support via its mounting holes. It is important to leave enough space around the pump for access to allow maintenance and adjustment. Do not install the pump in a location where the ambient temperature is likely to be below or above the stator's minimum and maximum temperatures (see temperature table, Paragraph 1.2.2). For an outdoor installation, it is advisable to provide shelter above the equipment, and protection from freezing. Warning: it is essential to install the pump horizontally because the mechanical seal may be damaged if it is installed vertically . We also advise the installation of a removable connection piece to allow easy servicing of the entire motor-pump. A pressure relief valve or pressure-sensitive switch and a pressure gauge at the discharge will protect the pump and display its operating specifications. PCM has a wide range of accessories available - contact us for any requirement you may have.

Recommended Accessories

Valve and Pressure Relief Valve (or Pressure-Sensitive Switch) When a valve is installed on the pump discharge pipe, it is essential to install a pressure relief valve or pressure-sensitive switch to protect the pump and the installation. Connected on a branch circuit off the discharge circuit, as close as possible to the pump and before the valve, it acts in the event of accidental overpressure to return fluid to the tank or send it to the drain, or to stop the pump (pressure-sensitive switch).

Tips for Optimum Pump Operation a) Except for very thick (i.e. viscous or concentrated) products, the suction end of the

pump must be located above the product to be pumped. b) It is preferable to have the discharge above and open to the atmosphere. c) Place the pump as close as possible to the suction point. d) If a valve is present on the circuit, it is ESSENTIAL to install a pressure relief valve

or pressure-sensitive switch.

NOTE.: Without protection on the circuit, a valve at the discharge is often the cause of handling errors leading to pump or pipework rupture.

1.3.2 Pipework Connection

Warning! All our pumps are supplied with a star assembly. Remember to connect the pump to earth.

For thermal protection, the setting value is the current indicated on the motor. After making all connections (single-phase or three-phase), start the pump (at low speed if possible) using a variable frequency drive or variable speed mechanism or hydraulic variable speed drive, if present, and check that the direction of rotation corresponds to the arrow affixed to the motor.

(33) 01 41 08 15 15

2. OPERATION

2.1 Commissioning

For pumps driven by a hydraulic variable speed drive, always install the pump in a horizontal position.

2.1.1 Before Start-Up

Check the following: – Hydraulic variable speed drive, variable speed mechanism or reducing gear filled with lubricant, – Direction of rotation corresponds to direction indicated on the pump, – Product to be pumped is present in tank, – All valves installed on pipework are open, – Temperature of product to be pumped.

2.1.2 Start-Up

WARNING! Do not start up the pump when dry! Dry running damages the stator since it is lubricated by the product. Fill the pump body with liquid before starting up an empty pump.

NOTE: If the pump is drained temporarily, the small amount of liquid which remains in the pump is

sufficient to lubricate the stator. Switch the pump on. During the first few minutes of operation, check the following: – The liquid being pumped reaches the end of the discharge pipe, – No abnormal noise, – Fittings are watertight, – Parameters to be checked:

. Flow rate,

. Pressure,

. Viscosity of product,

. Temperature. These should correspond to the pump design parameters given in the technical description (see Section 4: Appendices). If not, consult PCM Customer Service Department.

2.2 Normal Operating Procedure

2.2.1 Start-Up Procedure

Before each start-up, check the following: – Presence of product, – Valves on pipework are open, − Switch pump on.

(33) 01 41 08 15 15

2.2.2 General Operating Precautions

Ensure that: - The pump is receiving a constant supply of the product, and power.

2.2.3 Shutdown Procedure

This shutdown procedure depends on the type of product being pumped. Refer to the specific characteristics on the technical description, Section 4: Appendices. The shutdown procedure is thus specified in the process operating diagram. Nonetheless, the minimum procedure is to switch off the pump, then close the suction and discharge valves.

Warning! For a product prone to settling, the pump must be cleaned before re-starting, to prevent pump rupture.

2.3 Operating Procedure in the Event of an Incident

In the event of operating irregularities, such as: − Pump does not start, − Pump does not prime itself, − Flow rate too low or irregular, − Pump stops, − Pump is not delivering, − Pump is abnormally noisy. Proceed as follows: − Shut down the pump according to the shutdown procedure given in Para. 2.2.3. − Hydraulically isolate the pump (suction, discharge). − See Para. 3.5: Troubleshooting.

2.4 Automatic Control

It is advisable to use devices that automatically enable or disable pump operation. For example, valves with open-position electrical contact, minimum level reading, pressure-sensitive switch, vacuum switch, dry running protection device, etc.

(33) 01 41 08 15 15

3.4.2 Cleaning External cleaning Remove any dirt that could damage the paint and corrode the pump. Internal cleaning Cleaning procedures and frequency depend on the specific application of the pump, and the product being pumped. In any case, the minimum procedure is described below. With the pump running, feed in the cleaning product that is compatible with the pumped product and pump materials at the suction end. Cleaning time is defined according to the process using the pump. When this time has expired, shut down the pump according to Para. 2.2.3. To clean out the inside of the pump body thoroughly, remove the drain plug (Item 110A) (there is no plug on the stainless steel version of the pump). Then replace it so that the pump is ready to be started up again.

3.4.3 Lubrication The pump does not have any lubrication of its own. The pump drive is supplied with oil (except for single motors in which there is no lubricant level to be checked). Check the lubricant level in the drive before putting the pump into service. The precautions to be taken for the lubrication of the drive, if the drive is lubricated, should be followed in the documentation supplied in the Appendices.

3.4.4 Torque The overall torque for the mounting hardware is 8.7 Nm for all screws on this pump.

Symptom Causes Solution

Pump does not start up

1) The stator is swollen 1) The material the stator is made out of swells on contact with the product being pumped. Check whether the material and the product are those indicated on the order. If not, contact our Customer Service Department.

2) The rotor drive system is broken but the motor is rotating

2) Determine the cause of the incident by checking points 1), 3), 8) and 17) then replace the faulty parts.

3) The product temperature is too high 3) See Paragraph 1.2.2

4) The fluid is sedimenting or precipitating in the pump body

4) Clean the pump body and rinse the pump after each use.

5) The solid bodies in the product being pumped are too large

5) Remove the solid bodies by sieving or consult our Customer Service Department to provide another pump.

6) The electrical installation is not compliant

6) Check the voltage of the mains supply, the motor connection, the calibration of the circuit breaker and the number of phases.

7) The devices driving the pump are broken or worn

7) Replace faulty parts and check the drive's load.

8) A foreign body is blocking the pump 8) Disassemble the pump, clean it and replace any damaged components.
