Drainage pumps Caliber SPC will help fill the tank with clean water, free the septic tank capacity from dirty liquid, pump out water from the flooded basement, drain the pool or water the garden. The range of submersible centrifugal pumps has models that differ in power or capacity. You can choose a device that matches the tasks of a particular situation.
Principle of operation and arrangement of drainage pumps Caliber
The principle of operation of the drainage pump Caliber, characterized by high efficiency, based on the action of centrifugal force. A rotating impeller on the impeller creates a vacuum of air. Water is drawn into the working chamber through the inlet of the pump unit, and then blades are pushed further through the discharge pipe.
Pumps Caliber SPC are available in lightweight and durable housings made of plastic or stainless metal. The device includes:
- pump unit;
- Electrical engine;
- electrical cable 10 m long;
- float switch.
Moving water raises sludge and heavy particles from the bottom. They are drawn in and carried along with the fluid. The size of the removed particles is limited by the size of the inlet located on the housing.
Lineup and Specifications
The industrial and manufacturing company Caliber produces more than three dozen models of electric pumps. The design of the devices is optimized for operation in aggressive environments. Having tested the device in difficult conditions and making sure of the advantages, many users leave positive feedback on the caliber submersible drainage centrifugal pumps on the seller’s website.
Pay attention to the marking of models. It includes the most significant characteristics of the device. For example, in the name of the pump drainage Caliber NPC-1000 / 40P 00000050841:
- "Caliber" - manufacturer;
- "NPC" - a series of "centrifugal submersible pump";
- "1000" - rated power of the device W;
- "40" - the maximum allowable size of the absorbed solid particles in millimeters;
- “P” - means that the case is made of plastic, models with cases made of stainless steel are marked with the letter “H”.
Modifications of drainage electric pumps Caliber are designed to work in liquids of various degrees of contamination. The marking of devices for pumping clean water indicates a particle size of not more than 5 mm, for example a submersible drainage pump Caliber SPC 750/5 P 00000046473.
When removing dirty water, the permissible size of solid particles should not exceed 40 or 35 mm, as in the model of the drainage pump Caliber NPC-400/35 P 00000045330.
Models differ in technical characteristics optimized for work in various conditions:
- power varies in the range from 250 W to 1300 W;
- liquid lifting height from 5 m to 20 m;
- productivity is from 133 to 400 liters a minute;
- diameter of solid inclusions up to 40 mm;
- the maximum temperature of the pumped water is 40 degrees;
- weight 4 - 8 kg;
- price from 2000 rub. up to 6000 rub.
Most models have a convenient handle on the top of the case for moving from place to place. The tight case reliably protects the electric motor from moisture hit. The float switch provides protection against dry running, turns off the device when the water level drops.
Criterias of choice
When choosing a pump option for use in your home, you should pay attention to the following parameters:
- depth of immersion in the tank;
- device power;
- performance per unit of time;
- the height to which water can be pumped;
- temperature of the pumped water;
- purpose - for clean or dirty water, permissible diameter of solid particles;
- noise level at work.
Among the drainage pumps Caliber, you can choose a model for a house or garden with optimal characteristics. The drainage device must meet difficult operating conditions in order to operate for a long time and without accidents.
Installation Features
Caliber pumps are sold ready to go. The pump sinks to the bottom of a reservoir or reservoir to a depth of 8 meters. Liquid suction occurs through the bottom. Installation of a submersible drainage pump is carried out using a cable or pole. The fluid is pumped out through a flexible hose or pipes connected through an outlet pipe. No suction line required. It is connected to a network with a voltage of 220 V.
Advantages and disadvantages
The benefits of Caliber submersible drainage pumps include:
- light weight and ease of movement;
- high productivity from 8 to 25 cubic meters of water per hour;
- permissible particle size up to 40 mm;
- noiselessness;
- automatic shutdown.
The disadvantages include the complexity of maintenance: to inspect the device, it must be completely removed from the water. In the lineup there are no surface-type devices.
Owner reviews
In their reviews, customers note the simplicity and reliability of the Caliber pumps, which are easy to start even after wintering in the drainage well and pump very large fragments. Everyone praises the low noise level. Among the advantages, users call a low price.
At the drainage pump Caliber NPC-350B 00000050840, designed for pumping clean water from barrels or pools, customers noted the low quality of the connecting tubes used for fastening on the barrel. There were no complaints about the operation of the engine.
Buyers rated the model of the drainage pump Caliber NPC-400 / 35P 00000045330 the top three. These models easily fail, the float switch does not work, the performance does not match the declared one.
Among the shortcomings, several people called the unpleasant smell of plastic, from which the caliber pump housing is made. However, they immediately made a reservation that in the conditions where the pump is operating, this criterion is not important.
Consumers agreed that it is better to pay extra, but to buy a more expensive and high-quality model that will last longer.
