Basic issues about the centrifugal pumps
Centrifugal pump or a flow centrifugal pump to be precise, should be seen as the device where a rotor transfers the energy to have received from the engine into the liquid causing the liquid flow and volume increase [pressure increase] which leads to suction at the pump input.
Centrifugal pumps differentiate between draught pumps. The difference is that a draught pump outputs the pressure supplied by the power installed in the pump with virtually unchanged efficiency but a centrifugal pump outputs the pressure supplied by the power installed in the pump, however the height raise decreases

Pump efficiency [Q]
It is the liquid volume to be pumped in a time unit. The efficiency is described with m³/h or l/min.

The height raise [H]
It is the parameter describing a centrifugal pump which change the velocity energy into the location energy which is the height and is described with the water column in 'mm' [mH₂O]

Power consumption [P]
It is the power to be consumed by the pump while work

Revolutions [n]
It is the amount of shaft revolutions per one minute [rev/min]

Pump efficiency [η]
It is the ratio of the payload power to the consumed power onto its shaft and it is described in „per cents” [%]. The efficiency of high output power pump is greater than that one of a low output.

Suction abilities
A centrifugal pump is openly designed – rotating components do not touch or adjoin one another which helps to keep a pump in cleanness but disables a pump from to suck any liquid. A centrifugal pump should be installed so that a sucked agent can flow into a pump. A suction tip should be below the sucked liquid surface.

When one selects a proper pump, one should pay attention to the fact that a pump will be as efficient as an input pipe pressure. It will be very good if a pump work-point [Q, H] equal to its maximum efficiency. If the pump maximum efficiency is exceeded the power consumption raises as well as the cavitation phenomenon of the pump input and a pump itself. If the efficiency is close to none, for example as a result of the pressure side resistance, heating the liquid inside of the pump may occur.

Pressuring heavy liquid
Pressuring the liquids of specific gravity greater than water specific gravity do not impact on a pump height rise decrease but brings higher power consumption. It is the result of the pressure to work on pump shaft blades. It often happens that the liquids with higher specific gravity go together with increased stickiness.
Pressuring sticky liquid
Pressuring the liquids with the stickiness higher than that one of water causes the pump parameters decrease, efficiency [Q] and height rise [H] to be precise. The power consumption increases as a result of the work needed to overcome the inner friction of liquid and a rotor and other pump components inside.
When pressuring the liquids with the stickiness higher than that one of water and when a pump is stifled simultaneously, a given liquid height rise is close to the height rise specified for water. When there pumped liquid efficiency increases, the heights rise decreases.
Comparing the profiles is possible being based on nomograms to define a pump parameters decrease depending on pumped liquid stickiness, its efficiency and the height rise.

The current frequency influence on a three-phase engine
,f – current frequency [Hz], p - amount of poles vapour [an engine with 3000 rev/min is 1 poles vapour], n – engine revolutions [rev/min]

The pump revolutions changes influence on its efficiency, the height rise, power consumption [Q, H, P]

The pump shaft diameter changes [d] influence on its efficiency, the hight rise, power consumption [Q, H, P]

The SPOMASZ food pumps applications

The WPs centrifugal pump

A pump is applied in all the liquids to be used in the food industry where a low plumbing pressure and low efficiency as well as the low height rise are needed.

The GH type pump

A pump is applied in the plumbing where the food safety is the highest priority.
Food product in liquid state at stickiness at 1000cP transportation, such as:

• dairy industry [fresh and sterilized milk, whey, mixed ice-cream]
• fruit and vegetable processing industry [non- and transparent juice and sap]
• pharmacy

The GA type pump

A classic pump to have been applied in the dairy plumbing for a few ten years. It is reliable, its design and the trunk shape ensures the sealing durability.
The pump is the only centrifugal pump to be made of AISI 304 steel to be found in the food pumps assortment. All other pumps are made of AISI 316L [1.4404] stainless steel. The pump has a closed rotor.

The GU13 and GU14 pumps

The pumps are used to transport dense food liquid to contain no more than a half of dry substance or other food liquid with similar properties with the limit temperature of 95°C. It is equipped with open rotor. The pumps have classic soft graphite sealing. It may work in plumbing with low infrapressure.

The GU15 and GU15/4 pumps

The pumps are used to transport dense food liquid to contain no more than a half of dry substance or other food liquid with similar properties with the limit temperature of 95C. Because of increased height rise it can be used to pump agents by plate or pipe vapours or other devices with high resistance.

The G GU-30/30, GU-30, GU-50/15 GU-46, GU-42, GU-50, GU-70 pumps

A big family of centrifugal pumps used to transport food agents at stickiness of 1000cP.
