Description

Micro Peripheral Pump-HPE

Micro Peripheral Pump is suitable for use with clean water and liquids that are not chemically aggressive towards the materials.

As a result of their reliability and the fact that they are easy to use, we use these pumps in domestic and civil applications such as the distribution of water in combination with small and medium sized pressure sets, for transferring liquids and for the irrigation of gardens and allotments.

You should install the pump in an enclosed environment, or at least sheltered from inclement weather.

Performance range:

• Flow rate up to 160 l/min (9.6 m3/h)
• Head up to 56 m

Application limits:

• Manometric suction lift up to 7m
• Liquid temperature between -10°C and +90°C
• Ambient temperature up to +40°C

What is a Micro Peripheral Pump ?

We design the centrifugal pump is a mechanical device to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers.  Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.  The action of the impeller increases the fluid’s velocity and pressure and also directs it towards the pump outlet.  We design the pump casing to constrict the fluid from the pump inlet, direct it into the impeller and then slow and control the fluid before discharge.

What are the main features of a centrifugal pump?

There are two main families of pumps: centrifugal and positive displacement pumps.  In comparison to the latter, centrifugal pumps are usually specified for higher flows and for pumping lower viscosity liquids, down to 0.1 cP.  In some chemical plants, 90% of the pumps in use will be centrifugal pumps.

What are the limitations of a centrifugal pump?

The efficient operation of a Micro Peripheral Pump relies on the constant, high speed rotation of its impeller.  With high viscosity feeds, centrifugal pumps become increasingly inefficient: there is greater resistance and a higher pressure is needed to maintain a specific flow rate.  In general, centrifugal pumps are therefore suited to low pressure, high capacity, pumping applications of liquids with viscosities between 0.1 and 200 cP.

Slurries such as mud, or high viscosity oils can cause excessive wear and overheating leading to damage and premature failures. Positive displacement pumps often operate at considerably lower speeds and are less prone to these problems.

High speed of a centrifugal pump’s impeller can damage any pumped medium.

In other words sensitive to shearing (the separation of emulsions, slurries or biological liquids).  In such cases, we prefer the lower speed of a positive displacement pump.

A further limitation is that, unlike a positive displacement pump.

A Micro Peripheral Pump cannot provide suction when dry.

Additionally, if the feed pressure is variable, a centrifugal pump produces a variable flow. A positive displacement pump is insensitive to changing pressures and will provide a constant output.  So, in applications where require accurate dosing , prefer a positive displacement pump.
