Fecal pump with chopper

For private houses and cottages, as well as various enterprises of institutions, the issue of wastewater treatment is always very urgent. For this purpose, there is a special device - a fecal pump. From a conventional drainage pump, it differs in that it is able to pump water, where often there are various kinds of solid particles.

Fecal pumps are of various types, but they can all be classified according to such an important principle as the presence or absence of a chopper. This useful device will help you avoid unnecessary clogging of sewer pipes. So, let's look at the features of pumps equipped with a chopper, and their differences.

Types of fecal pumps with a shredder

As is known, pumps for faeces come in the following forms:

1. Submersible - helps drain discharges from the household septic tank. It is made of stainless steel or cast iron, resistant to aggressive environment. In the design of the submersible pump there is a float device, so that the operation of the device is automatic. This pump should be located below the sewage level, in fact at the bottom of the tank. Such units have a power of up to 40 kW. Submersible models of fecal pumps with a shredder are easy to operate, they are often purchased for dachas.
2. Semi-submersible pumps are less versatile because they are more sensitive to the size of solid impurities that can be contained in the effluent. The maximum size of such a particle is 15 mm. This is not enough, but many successfully use this pump, confirming the fact that such capacity is quite suitable for domestic needs. Please note that it is technically impossible to supply such pump models with an additional chopper, so your choice of a semi-submersible device should be initially justified.
3. Surface pump is the lowest cost among all listed models. In addition, it is more mobile, because it is located on the edge of the tank, and only the hose is immersed in the container. But the surface type of pumps has its own significant drawbacks: it is a small capacity (diameter of solid particles is not more than 5 mm) and relatively low power of the device itself. It should also be noted that when operating at low temperatures in the winter, the drains entering the hose into the unit have the property of freezing, making it difficult to operate the device and leading to breakdowns. Therefore, a submersible pump is worth buying if there is a structure near the waste tank for stationary operation of the device.

And now let's look at the pump models of several of the most popular manufacturers.

For example, the German Grundfos SEG pump is equipped with a cast iron shredder, two thermal relays protecting the engine against accidental overheating, and a special device that provides adjustment of the impeller of the device. Use this model most often for a long pipe system having a large extension and a small diameter up to 40 mm inclusive.

The model "Sprut" has an optimal ratio of the quality of the device and its price. It has both a float switch and a 6-meter supply cable. Conveniently, this pump for fecal water, equipped with a chopper, is able to operate autonomously. The cutting mechanism of the model, judging by the reviews, works efficiently, crushing large particles well. However, keep in mind that the operating temperature should not exceed 40 ° C, so this pump can not be used for sewage pipes, where drains from the washing machine or dishwasher .
