Get a wide selection of industry-leading electric and solar water pumps from reputable Zambian suppliers. Brands available include but not limited to Dayliff, Grundfos, Wilo, Pedrollo, ETEC, Vossche and Sulzer. You will also find a wide range of approved and reliable quality spares - genuine, OEM and replacement parts as well as related accessories. No matter what your requirements are, you will definitely find a pump or part that will meet your specific pumping needs. All pumps come with a warranty and some suppliers provide installation services.
The main components in a pump are the casing, impeller, backing plate, shaft and shaft seal, and the motor adapter. Some pumps have the backing plate as part of the casing in which case you would have a removable cover. The shaft seals are a critical part of the pump and selecting the right seal is an important step.
Its most basic components include the hub/pulley, bearing, body/house, seal, and impeller.
- The Hub or Pulley. A water pump's pulley is designed to transfer the drive belt's movement into the bearing spindle.
- Spindle bearing.
- Body.
- Seal.
- Impeller.
Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valve less pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.
Flow: Also referred to as flow rate, this describes the volume of fluid which a pump can produce in a given amount of time. Usually measured in cubic metres per hr (m3/hr), litres per second (L/sec) or litres per minute (L/min), the higher the number the larger the volume of fluid a pump can produce per second.
A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips.
Centrifugal pumps are Single-stage, Two-stage, or Multi-stage. Main Types of Pumps: Centrifugal and Positive Displacement.
An impeller is a rotating iron or steel disc with vanes in a centrifugal pump. Impellers transfer energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid radially outwards from the centre of rotation.
Motor is an electrical machine. The main function of pump is to push the liquid from low level pressure to high level. The main function of motor is to change the energy from electrical to mechanical. A pump operates with a motor otherwise an engine. The motor operates with an energy source.
Liquid can only move on its own power, and then only from top to bottom or from a high pressure to a lower pressure system. This means that energy to the liquid must be added, to moving the liquid from a low to a higher level. To add the required energy to liquids, pumps are used.
Simply stated, a heat pump is a type of HVAC equipment that can provide both heat and cooling. A heat pump uses mechanical energy to remove heat from the air and move it either inside or outside, depending on whether your space needs heat or air conditioning.
While a motor is itself a driving mechanism which can be used to power another device, a pump is a mechanical device which requires a driving mechanism in order to function. Motors use electrical energy to produce mechanical energy, while pumps in Lethbridge use mechanical energy to perform work.
A positive displacement (PD) pump moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms or vanes.
