Wastewater, surface water and groundwater are often heavily contaminated with impurities, which interferes with their removal. Maintaining the proper view of the area adjacent to the building requires the use of special equipment. The Karcher drain pump is designed to pump liquid containing large particles of dirt.
Lineup and Specifications
The manufacturer presents a large line of drainers for domestic and household needs of the SDP and SP series. To prevent leakage from the system, they have reliable threaded connections. In addition, the devices have removable filters so that you can pump out the liquid to the lowest possible level.
- The design features of SDP allow pumping water flow with inclusions up to 20 mm. The pressure on the weakest unit is 0.5 bar. Each device has: ceramic mechanical shaft seal; a special tight-fitting system for the possibility of simultaneously connecting several hoses to the unit; float switch. Depending on the model, the device can fall by 7-9 meters. The numbers included in its name indicate productivity.
- When developing SP, the latest engineering achievements were used. The equipment of this series is capable of passing liquid with inclusions up to 30 mm. All devices are identical in design, with the exception of the SP7Dirt Inox. This is the most powerful device. Its movable mesh filter allows you to adjust the parameters of the transmitted particles, in addition, it has an individually adjustable level sensor.
- The power of all drainers varies in the range of 250 - 750 watts. The injection volume is 5.5 - 15 m3 / hour. Head can reach 8000 m. Depth of immersion is not less than 7 meters.
- Models made of stainless steel are labeled “Inox,” and the Level Sensor indicates the presence of a breaker.
The length of the power cable is standard and equal to 10 meters. Due to the high build quality and reliability of the materials, the Karcher submersible drainage pump for dirty water can be used in difficult conditions at high loads. The company gives a long guarantee for the manufactured equipment.
Criterias of choice
Flow rate, feed height, power, throughput and the availability of working with large particles, the presence of a thermal relay on the motor - all these criteria should be paid attention to when choosing a unit.
To make the drainage device easier to attach to the system, you need to use special adapters or connecting elements.
The main emphasis is on equipment performance - the device should work without overload. The calculation of capacity in liters can be performed according to the formulas:
- Round tank = (D1 x D2 x C) x 0.78 x 1,000;
- Rectangular catchment basin = (A x B x C) x 1,000;
where D1 and D2 are the diameters, A is the length, B is the width, C is the average depth.
The difference in the heights of the surface of the liquid, the cross-section and compatibility of the hoses, as well as the size of the solid particles, and the location of the suction port have an effect on the efficiency and speed of pumping.
The company is engaged not only in the production of pumping equipment, but also develops and produces related kits and parts for it.
Installation Features
The classic options for pumping equipment do not have complex components and are designed for everyday use in everyday life. Of the additional options, entry-level devices have only a portable handle and a connecting pipe.
The folded legs and continuously adjustable switching level of the units make it possible to remove moisture up to 1 mm from the surface. The control system is automatic and touch. In the first case, a float is used, and in the second, an electronic sensor is triggered.
The nuance of the work of drainage machines is their tendency to overheat. Therefore, it is necessary to ensure that the electrolytic system or float switch is timely activated and blocks the operation of the engine.
The higher the level of equipment - the more difficult the setup of the device. More powerful models have a professional seal, adapter, hose adapter and air vent button. In addition, they can be equipped with a check valve and an ISU to equalize performance in accordance with operating conditions.
Advantages and disadvantages
Units can be used almost around the clock. A plus is the ability to use equipment at the professional level, while they work from a single-phase network.
- The level sensor allows you to automatically start the device and turn it off, and a removable filter ensures the possibility of downloading, if necessary, low location of the suction port.
- The intelligent system of devices with remote control is able to adjust them to the required parameters of depth and liquid.
- Devices can pass compositions without pre-filtering with large solid particles.
- The warranty period of the units is 5 years.
The only disadvantages include the cost, which is an order of magnitude higher than domestic devices. However, the Russian or Chinese market cannot offer a unit of similar quality.
Cost of pumping equipment
This brand of a European manufacturer has established itself on the best side and is in demand among homeowners.
The price of the Karcher submersible drainage pump used for dirty water depends on its modification and available options.
The price range on average starts at 3500 rubles. and grows in direct proportion to the capabilities of the devices. However, performance, low power consumption, ease of maintenance and a long service life fully offset the cost of the purchase.
