There are a number of important considerations to make when sourcing a submersible water pump. These factors are essential informants of a buyer’s decision. This article elucidates how these factors weigh out in the selection of a submersible water pump in Kenya. It equips you with knowledge on what to look out for in this endeavor.
Introduction
Selection of a good water pump should be an easy process when you are aware of what qualifies for one. Discussed below are essential measures to making an informed decision on choice of a submersible pump. They include factors directly related to pump features as well as external factors with effect on its functionality.
Key considerations for a submersible water pump
Motor consistency
It is advisable to go for a motor that runs continuously as opposed to intermittently. It is also imperative to verify that this does not adversely affect the functionality of the pump for instance through overheating or burn.
Specific viscosity/gravity
This is the density of water to that of the liquid being pumped. It is a definitive factor to pump performance. Changes in specific gravity vary the power of the pump. Submersible water pumps do not require liquids with high viscosity as they tend to cause overload on the shaft power.
PH and chemical composition of water
This is essential in determining any corrosive or other adverse effects the water may have on exposed parts of the pump. Materials used in the pump’s production ought to also be examined to determined compatibility with chemical components in the water. For instance, aluminium and cast iron components are highly prone to deterioration on exposure to high PH while stainless steel is more durable.
Motor protective gear
High quality submersible water pumps for sale in Kenya are equipped with protective features to safeguard from failures. Common failures range from water incursion to electric related failures. It is imprudent to run a submersible pump without proper voltage as it leads to irreversible damage. Devices such as thermal protectors are installed to these pumps to gauge internal current and temperature and prevent damage in instances of power surges and voltage imbalance. Mechanical seals keep water out of the motor preventing water incursion.
Capacity
This refers to the volume of water being moved and the rate at which it is being moved. It is important to be aware of the optimal capacity for your utility needs. For instance large farms may require larger capacity pumps compared to smaller farms.
Distance and elevation
The height and length of utility site from the water source is also an essential consideration. This directly determines pressure requirements of the pump to ensure efficiency. For longer distances, pumps resistant to gravity and loss of friction are better suited.
Source of energy
It is important to consider your main source of power. In this case, electric pumps are best suited for sites where electricity is the most accessible energy source.
Choosing a submersible water pump is made easy by understanding your utility needs as well as understanding functionality and maintenance requirements of one.
