Pool Pumps

Rhino Pools only installs Speck pumps as they are built to the highest German specifications and offer a 2 year manufacturer's warranty. Speck's range of pool pumps also offer the highest flow rates in their class and spares are easily obtainable in the unlikely event of the need of a pump repair. Speck Pumps has a branch in Pretoria which means that technical support is at hand and warranty claims are dealt with speedily and effectively.

A good quality pool pump of the correct strength for your pool size (ie: to achieve an optimal flow rate) is crucial for trouble free pool maintenance. Over the past 14 years Rhino Pools have established a great relationship with Speck pumps due to the awesome reliability and dependability of their pool pumps. We have systematically eliminated all other brands of pool pump due to their poor quality, bad design and terrible after sales service.

We are supremely confident that Speck Pumps are the best swimming pool pumps on offer in SA and for the same price as any other pump available, the value for money couldn't be better.

Pumps and Filters

Having the correct pump installed at your pool is essential to the optimal functioning of your filtration system. If the pump is too small to push the volume of water contained in your swimming pool within a given time then the chemicals will not be circulated sufficiently for efficient sanitation of your pool water.

Pool pumps have specific flow rates which indicate the speed and volume of water being moved by the pump at a given point in time. Flow rates are a consistent value provided there are no external obstructive forces. These obstructions would the filter, the Barracuda (pool vacuum) and the 90° elbows along the piping system.

The filter, if the sand is old, dirty and clogged, causes back-pressure in the pump as the flow of water is obstructed within the filter itself. This is evident when the pool vacuum pipe is pushed out of the weir vac lid at the instant that the pump switches off. Another influencing factor in this phenomenon would be if the air breather pipe (a small diameter pipe inside the filter which allows the filter to equalize the pressure inside) is also blocked.

The length of pipe along which the water needs to be pushed (ie: from the pump to the pool) , along with each of the 90° elbows along that length are definite obstructions in the system. Each 90° elbow provides the same amount of resistance as roughly 6m of 50mm pipe. This means that the further the pump is from the pool and the more complex the piping system is (ie: number of elbows) going back to the pool ( along the return pipe), the more resistance in the system and therefore the less efficient the system will operate.

The pool vacuum which is on the suction line (weir pipe) has a different kind of negative effect on the flow rate as the pump has to work extra hard to suck water through not only the underground suction line, but also the pool vacuum pipe. This means that the longer the pool vacuum pipe is, the less suction the pump will create and ultimately the less effective the system will operate. By plugging in the vacuum pipe you're essentially lengthening the suction line.

Locating the weir in the middle of the longest side of the swimming pool will allow for a shorter vacuum pipe.

In conclusion, it is important to make sure that your filter sand is replaced at least every 2 years (at same time unblocking the air breather pipe), the pool pump is located as close to the pool as possible, and that the weir is located as close to the middle of the pool as possible. This combination of regular servicing of the pool filter and correct placement of the pump and weir will certainly make pool maintenance a breeze.

Good luck and good swimming!
