Without swimming pool pumps, the mainstay and most essential piece of
equipment of a swimming pool infrastructure, it would be impossible to maintain
the hydraulic flow and pressure needed to circulate water in that
infrastructure. By way of electrically powered swimming pool pumps a constant flow of pressurised water through
a pool or spa’s plumbing system and related equipment can be maintained.
Pumps are of course the main element
of a pressurised water delivery system to a swimming pool or spa but other
equipment which maintain pool and water integrity include heat exchangers, heat
pumps, water pumps and filtration systems in addition to chemical dosing
equipment. However, without the pump the aforementioned equipment items are
pretty much redundant.
Pumps for circulating the water round
a spa or swimming pool vary by degrees; as an example, the size and water
volume of a pool or spa will dictate the type of pump and also its power ratio
and output. The larger the pool size and the greater the volume of water will
mean the larger the pump capacity which will be required to efficiently
circulate the water around the system.
As well as the pump size in relation
to the volume of water being taken into account, you also have to consider the
required flow rate with respect to turnover time. Depending on the size of the
delivery pipe work and the length and volume of pipe work, this will have an
effect on the dynamic head (the friction loss
due to piping, fittings and equipment) of the system.
There are basic mathematical
equations which pool designers and installation companies use to determining
the appropriate pump and related peripheral equipment size, placement and
ability to complete the job in hand. The simplest is of course the volume of
water in the pool using a simple depth x width x length of the pool equation.
Then of course you need to consider
the amount of pipe work and the size of filters and heat exchangers in
determining the type and/or size of pump required on any given system. However,
to gauge accurately the operating parameters of any pool it is far better to
engage the services of an expert; in so doing, you will maximise the working
life of any equipment in use on the system, as well as maintaining pool health
for longer.
