FLYGT MP-3067 PUMP
Safety Precautions
Before starting work on the pump, make sure that the pump is isolated from the power supply and cannot be
energized.
NOTE! This applies to the control circuit as well.
The following points are important in connection with work on the pump:
-
Make sure the pump has been thoroughly cleaned.
-
Observe good personal hygiene.
-
Beware the risk of infection.
-
Follow local safety regulations.
The pump is designed for use in liquids which can be hazardous to health. In order to prevent injury to the eyes and
skin, observe the following points when working on the pump:
-
Always wear goggles and rubber gloves.
-
Rinse the pump thoroughly with clean water before starting work.
-
Rinse the components in water after disassembly.
-
The oil housing may be under pressure. Hold a rag over the oil casing screw (oil plug) and the
inspection screw to prevent splatter.
Proceed as follows if you get hazardous chemicals in your eyes:
-
Rinse immediately in running water for 15 minutes. Hold your eyelids apart with your fingers.
-
Contact an eye specialist.
On your skin:
-
Remove contaminated clothes.
-
Wash your skin with soap and water.
-
Seek medical attention, if required.
Make sure the pump cannot roll or fall over and injure people or damage property.
Inspection
Regular inspection and preventive maintenance ensure more reliable operation.
The pump should be inspected at least once a year, but more frequently under sever operation conditions.
Under normal operating conditions, the pump should have a major overhaul in a service shop at least every third
year for permanent installation and every year for portable pumps.
If the pump is new or if the seals have been replaced, inspections is recommended after one week of operation.
Regular check of the condition of the lifting handle and chain is important.

Pumps in hot water applications shall undergo inspection or overhaul at a service shop as follow, depending on the
time they have been submerged in the hot water:
Temp.
≤ 70°C
(160°F)
≤ 70°C
(160°F)
≤ 90°C
(195°F)
Mode of Operation

If the motor is three phase, the rotation of the impeller must first be checked. With the pump removed from the basin and lying on its side with the inlet in view, quickly turn the pump on and then off.
  • Page 21 4. Unscrew the four hex head cap screws and remove pump base. Use care not to damage O-ring if it is to be reused. 5. Radial cutter and axial cutter are now exposed. If checking for clogging, these parts can now be cleaned and inspected without removing them from the shaft.
  • Page 22 5. To reassemble, clean and inspect all parts. Replace any that show evidence or wear. Starting with the volute with bearing, insert the two lip seals in the housing. With the volute bearing not turned up, install the thrust shoe retainer, three thrust shoe segments, a carbon disc and retainer washer. Carefully insert rotor and shaft to prevent carbon disc damage, splined end down, through the thrust bearing group and the lip seals.

  • Page 26 CONDITION PROBABLE CAUSE Red light comes on at control box. This indicates some water has leaked past the lower seal and has entered the seal chamber and made contact with the electrode probe. Pump must be removed from basin within approximately two (2) weeks for replacement of lower seal.
  • Page 27 MYERS WG30 GRINDER PUMPS STARTING THE SYSTEM 1. Open gate valves on discharge piping. 2. Set pump switches at control box to auto position and turn on power. Fill sump with water until controls start pump. Allow pump to operate until level drops, stopping pump. 3.
  • Page 28 If amp readings are higher than listed, it indicates voltage may be higher or lower than normal or that pump grinder may be clogged with trash causing extra load on motor. CHECK LIST IF PUMP DOES NOT OPERATE PROPERLY CHECKING FOR MOISTURE IN MOTOR – Use ohmmeter and set on highest scale. Readings on the large power cord between any of the conductors red, black, white to green conductor or motor shell should be more than 500,000 ohms.
