BOOSTER PUMPS

FROM KÄRCHER:

SIMPLY CLEVER!

The Kärcher Booster Pump range provides the ideal conditions for luscious plant growth and an efficient and convenient supply of service water for home and garden. The Booster Pumps allow you to access alternative water sources with optimum results (for example watering the garden or flushing the toilet).

Multistage hydraulics ensure that Kärcher submersible pressure pumps can pump well water, ground water, rain water and spring water with the necessary pressure. The Kärcher barrel pump allows you to water your garden in an ecologically responsible way directly from your water barrel.

BOOSTER PUMPS

A RELIABLE PROCESSED

WATER SUPPLY.

A glance at the latest water bill will show that drinking water is becoming more and more expensive. So why not use low-cost water from alternative sources?

Booster Pumps from Kärcher offer the right solution for every purpose. Rainwater and groundwater are best used in the washing machine, for flushing the WC and for watering the garden.

The result: a reliable processed water supply – and a good feeling.

TECHNICAL INFORMATION

CALCULATION OF THE

PUMP CAPACITY.

The decisive criteria here are the flow rate and delivery pressure

(= delivery height). You can use the calculated values to select the most appropriate pump from the pump performance curve.

Example for the calculation of the right BP Home & Garden pump:

Q = flow rate

1. You must first determine the total volume of water required for all of the other points of use that require water at the same time. The guidelines for consumption are: Toilet flushing cisterns = 4 l/min, washing machine = 10 l/min, watering the garden = 10 l/min per sprinkler, cleaning work = 8 l/min.

2. The consumption values that are to be used simultaneously, must be added together. (Example: use of the washing machine, plus the use of two sprinklers, while also carrying out cleaning work => 10 l/min + 2 × 10 l/min + 8 l/min =

38 l/min).

3. However, since the points of use are not constantly in use, only 50 % of the total consumption is taken into account as a usage factor.

(Example: => 38 l/min × 0.5 = 19 l/min. This means a demand of roughly

1,150 litres per hour; 19 l/min × 60 min).

H = Required pump pressure / delivery height

The delivery height required for the pump combines the suction height HS + pumping height HF + required operating pressure in water column metres HW. An additional 15 % is added at the end to compensate for any loss in performance.

1. The suction height (HS) is the height difference between the lowest water level to the pump (Example: water level in the cistern is 4 m below the pump).

2. The maximum pump height (HF) is the difference in height between the pump to the highest water supply point (Example: 1 × WC flushing tank is on the second floor at a height of 5 m from the pump).

3. Any value from 1.5 bar is usually sufficient for the minimum operating pressure

(HW). This value must be converted into water column metres

(0.1 bar = 1 metre) (Example: 1.5 bar × 10 = 15 m).

4. Friction losses and resistance in the pipelines are factored in with a value of

15 % (line resistance). (Sample calculation: Required lifting height (H) =

4 m + 5 m + 15 m = 24 m + 15 % = 27.6 m).

RESULT OF

EXAMPLE CALCULATION.

For the example, you must choose a pump that delivers at least 1,150 l/h with a 27.6 m delivery height. The power of a BP 3 Home & Garden is required here.

1m = 0,1bar

Home & Garden

H = (HS + HF + HW) + 15 %

H = required delivery height of the pumps

HS = suction height

HF = pump height

HW = working pressure in meters of the water head (mWS)

15 % = conduction losses due to length of pipe, connections u.a.

Q = V1+ V2 + V… × 50 %

Q = required capacity of the pump

V1, V2, V…

= outlets

50 % = usage factor

TECHNICAL INFORMATION

FINDING THE RIGHT PUMP.

The pump curves in the diagram show the relationship between flow rate (horizontal axis) and lifting height (vertical axis). The flow rate varies according to lifting height (height difference between water level and hose end / water outlet). In principle: the flow rate falls as the lifting height increases. The pump curves are based on theoretically calculated values which are highly dependent on the length and diameter of the hose used or of the pipework.
