Drainage pumps Caliber SPC will help fill the reservoir with clean water, free the septic tank from the dirty liquid, pump out water from the flooded basement, drain the pool or water the garden. In the series of submersible centrifugal pumps, there are models that differ in power or performance. You can choose a device that matches the tasks of a specific situation.
The principle of operation and design of drainage pumps Caliber
The principle of operation of the drainage pump The high efficiency caliber is based on the action of centrifugal force. The rotating impeller on the impeller creates a vacuum. Water is drawn into the working chamber through the inlet of the pumping unit, and then by the blades it is pushed further through the discharge pipe.
Pumps Caliber NPTs are produced in light and durable cases made of plastic or stainless steel. The device includes:
- pumping unit;
- Electrical engine;
- electric cable 10 m long;
- float switch.
Moving water lifts silt and heavy particles from the bottom. They are drawn in and carried along with the liquid. The amount of removed particles is limited by the size of the inlet located on the body.
Model range and technical characteristics
Pay attention to the marking of the models. It includes the most significant characteristics of the device. For example, in the name of the drain pump Caliber NPTs-1000 / 40P 00000050841:
- "Caliber" - manufacturer;
- "NPTs" - series "submersible centrifugal pump";
- "1000" - rated power of the device, W;
- "40" is the maximum permissible size of sucked 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 varying degrees of contamination. The marking of devices for pumping clean water indicates the size of solid particles not exceeding 5 mm, for example, a submersible drainage pump Caliber NPTs 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 NPTs-400/35 P 00000045330.
The models differ in technical characteristics optimized for different conditions:
- power varies from 250 W to 1300 W;
- lifting height of liquid from 5 m to 20 m;
- productivity from 133 to 400 liters per minute;
- diameter of solid inclusions up to 40 mm;
- the maximum temperature of the pumped-over water is 40 degrees;
- weight 4 - 8 kg;
- price from 2000 rubles. up to 6000 rubles
Most models have a convenient handle at the top of the case for moving from place to place. The sealed housing reliably protects the electric motor from moisture ingress. The float switch provides protection against dry running, turns off the devices when the water level falls.
Criterias of choice
When choosing a pump option for use in your home, you should pay attention to the following parameters:
- the depth of immersion in the tank;
- device power;
- productivity per unit of time;
- the height to which water can be pumped;
- the temperature of the pumped-over water;
- purpose - for clean or dirty water, permissible diameter of solid particles;
- noise level during operation.
Among the drainage pumps Caliber, you can choose a model for your home or garden with optimal performance. The drainage device must be suitable for difficult operating conditions in order to work for a long time and without accidents.
Installation features
Caliber pumps are sold ready-to-use. The pump is submerged to the bottom of a reservoir or reservoir to a depth of 8 meters. The liquid is sucked up through the bottom. The submersible drainage pump is installed using a rope or pole. The liquid is pumped out through a flexible hose or pipes connected through the outlet. No suction line required. It is connected to a network with a voltage of 220 V.
Advantages and disadvantages
The advantages 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 size of solid particles 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. There are no surface-type devices in the model range.
Owner reviews
In their reviews, buyers note the simplicity and reliability of the Caliber pumps, which are easy to start even after wintering in a drainage well and pump very large fragments. Everyone praises the low noise level. Among the advantages, users call a low price.
For the drainage pump Caliber NPTs-350B 00000050840, designed for pumping clean water from barrels or pools, buyers noted the low quality of the connecting pipes used for fastening to the barrel. There were no complaints about engine operation.
The buyers rated the top three for the model of the drainage pump Caliber NPTs-400 / 35P 00000045330. These models easily fail, the float switch does not work, the performance does not correspond to the declared one.
Among the shortcomings, several people named the unpleasant smell of plastic from which the pump casing of caliber. However, they immediately made a reservation that in the conditions where the pump is working, this criterion is not important.
Consumers agreed that it is better to pay extra, but buy a more expensive and high quality model that will last longer.
