Electric Connection; Troubleshooting Guide - PYD Electrobombas Verti Serie Manual De Instrucciones

VERTI series vertical multi - stage centrifugal pump series : pump shell and impeller is
SUS304, SUS304 stainless steel for shaft, iron steel forinlet and outlet, advanced design,
the performance reach the advanced level of similar product, it have the features of light,
good looking, canker-proof antirust, high head, efficiency, endurance, etc.
VERTI series pumps motor is special product which have F class insulation,IP55 class pro-
tection, it use TPI bearing, UL&VDE certified capacitor, super mechanical seal, thermal
protection. VERTI Series pumps belong to non-selfpriming centrifugal pumps, input water
from the direction of shaft which is longer than normal motor.
VERTI series pumps is suitable for agricultural, industrial, gardening, air-conditioning, cool
circulation system, high building, water supply, boiler, fishing, and so on.
OPERATION CONDITIONS
VERTI pump is suitable for non-fire, explosive clean liquid which keep away from corro-
sive .the temperature of liquid : from +5 ºC to 70 ºC, max ambient +50 ºC ; Max. Working
pressure 1.5MPa, the max input pressure is limited by the max working pressure.
INSTALLATION
Notice:
• Do not install the pump in the sunbaked and any place.
• Install the pump to near the water as short as possible to reduce the suction.
• Position the pump using the brackets.
• Install the pump in a dry and ventilated place to ensure safe operation.
• Try to reduce the bend in pipe circuit as you can, the gradient should less than 2%.
• The connection of pipe circuit should be watertight, the pipes should be supported
separately.
• It's appreciated to install a vacuum meter and pressure meter in the suction and dischar-
ge port to observe the situation of operation.

ELECTRIC CONNECTION

Danger:
• Ensure the voltage(V), frequency(Hz), phase(PH) is conform with the ones marked on
the label. When the Voltage ±10% the inset thermal protector will terminate the motor.
• Pump should be reliably earthed.
• The cord should meet the requirements of current.
• Make sure the electric circuit is correct.
START, OPERATION AND STOP THE PUMP
Warning:
• Dry operation is prohibited in order to prevent the break of the mechanical seal and
others parts of the pump.
• It could rotate freely from the fan cover by screw driver.
FEATURES
• Turn on the pump, it should be turning clockwise from the fan cover end.
• Fill up the pump with water from the discharge valve.
• Turn on the pump, and set the discharge pressure to the required.
• Stop the discharge valve before stopping the pump and power.
MAINTENANCE
Notice:
• It is prohibited to start the pump frequently, the switch it should stop when the power
is interrupt.
• It is no allowed to use the suction valve to adjust flow.
• When the water is insufficient, the motor should stopped.
• If there is some irregular noise, please stop the motor and check.
• If the pump is not going to work for a long time or there is low temperatures, water
should be drained to avoid the pump body from damage and freezing.
TROUBLE SHOOTING GUIDE
SYMPTOM POSSIBLE CAUSE
Pump does • Motor blocked.
no turn • Voltage is not suitable.
• Fuse or thermal protection off.
Pump not • Too much head height.
pumping • The water level is too low.
properly • The bottom valve is not in the water.
• No water.
• Leakage of inlet pipe.
Pump running • Bottom valve blocked.
without head • The impeller is corroded.
• The bottom valve is not in the water.
• No priming water.
• Leakage of inlet pipe.
Flow obviously • Bottom valve blocked.
decreasing • Too much head height.
• The water level is too low.
• The impeller is seriously damaged.
Overheating • Voltage is not suitable.
of motor • Operation room not ventilated.
Pump stop • Motor blocked.
shortly after • Voltage too low.
start • Operation room not ventilated.
SOLUTION
• Disassemble connection pipe, send to service
center.
• Check voltage according to nameplate.
• Check fuse or thermal protection.
• Check if the height of installation match the
total head.
• Check the suction height.
• Adjustable inlet pipeline into water.
• Fill up the pump body with water.
• Check the leakage of pipe.
• Check the suction height and reinstall.
• Replacing the impeller.
• Enough water level for inlet.
• Put priming water into pump body.
• Check the leakage of pipe.
• Cleaning and replacing bottom valve.
• Check the installation height.
• Check the suction and reinstallation.
• Replacing the impeller.
• Contact electric power company to supply
stable voltage.
• Supply good ventilation.
• Dismantle the connection pipe and send to
service center.
• Contact electric power company to supply
stable voltage.
• Supply good ventilation.
