Application of Our Vortex Pumps HPE

Our HPE series peripheral pumps (vortex pumps) are suitable for handling clean water not containing abrasive particles and fluids, which are not chemically aggressive to the pump components. Those series pumps have features of reliable, economical, low maintenance and simple to use.

They are suitable for domestic applications and the automatic distribution of water from surge tanks, watering gardens and for boosting insufficient mains water pressure.

Warning of Peripheral Pumps

Before installing the pump, check the rotating parts of pump, make sure it could be turn freely as following:

Insert a screwdriver in the notch on motor shaft from the ventilation side, if there is a blockage, turn the screwdriver, tapping in gently with a hammer.
If the pumps not operated after long stopped, pls do as following:
1. Turn off the electric power
2. Turn the shaft in the back of motor with driver or something like that.
After the impeller could turn freely, operate the pumps as usual.

Installation of Peripheral Pumps HPE

The pumps must be installed in a dry well ventilated place, protected from unfavorable weather conditions and with an ambient temperature not exceeding 40℃.

Fix the pump in place on a solid flat surface using suitable bolts to avoid vibration.

The pump must be installed in a horizontal position to ensure that the bearing operate correctly. The pipes must always be supported using the related brackets to avoid transmitting stress to the pump body.

Take care not to damage any parts by over tightening the pipes when fitting them.

It is always good practice to install the pump as close as possible to the liquid to be pumped.

The inter diameters of the pipes must never be smaller than that of the mouth of the pump.

It is advisable to fit a foot valve on suction.

The intake pipe is completely airtight and immersed in the water by at least half a meter to avoid the formation of vortices.

For suction depths of over four meters or with long horizontal stretches, it is advisable to use an intake hose must slope slightly upwards towards the pump.

The diameter of the delivery pipe must be chosen to suit the flow rate and pressure at the take off points.

It is advisable to fit a non-return valve between the delivery mouth and flow rate adjustment gate valve to avoid danger water hammering in the event of the pump suddenly stopping.

This measure is compulsory if the delivery water column is over 20 meters.

When this pump is set up in the well which is easy to suck in sand. in this case, sand filter is required to fix, in order to prevent the defacement of the impeller in the pump head, it is normal that the water head fall down and the water flow decrease because of sand filter.

Electric Conection

Caution! Always follow the safety regulations. Scrupulously follow the wiring diagrams inside the terminal box. Electric installation must be carried out by skilled and authorized electrician who accepts all the responsibility for the job.

Ensure that the mains voltage is the same as the value shown on the motor plate and that there is the possibility of MAKING A GOOD EARTH CONNECTION.

For fixed installations, international safety standards require the use of isolating switches with a fuse-carrier base ensuring omni polar disconnection from the mains supply.

Single phase motors are provided with built in thermal overload protection and may be connected directly to the mains.

Three phase motors must be protected with special remote-control motor-protectors calibrated for the current shown on the plate. The permitted voltage of this pump is ±10% of the rated voltage, otherwise it will be the reason shortening the service life of the pump.

Starting Up

Before starting up, check that the pump is properly primed: fill the pump completely with clean water by means of the hole provided after having removed the filler cap on the pump body.

This ensure that the mechanical seal is well lubricated and that the pump immediately starts to work regularly.

Dry operation causes irreparable damage to the mechanical seal. After primed, the filling cap must then screwed back in order on carefully.

Switch on the power and check: for three phase motor, the turning direction should in a clockwise direction looking at the motor from the impeller side. If it is turning in the wrong direction, invert the connections of any two wires on the terminal board.

Precaution Our Peripheral Pumps

The peripherial pumps should not be started more than 20 times within one hour.

DANGER OF FROST: when the pump remains inactive for a long time at temperatures of less than 0℃, the pump body must be completely emptied through the drain cap to prevent possible cracking of the hydraulic components.

This operation is advisable even in the event of prolonged inactivity at normal temperature.

When starting after long period of inactivity, the starting up operation listed above must be repeated.

Maintenance and Cleaning

In normal operation, the pump does not require any specific maintenance. However, it may be necessary to clean the hydraulic parts when a fall in yield is observed. The pump must not be dismantled unless by skilled qualified personnel which required by the regulations in force. In any case, all repairs and maintenance jobs must be carried out after disconnected the pump from the power mains.
