Little Giant Pumps

Little Giant Pumps, developed by experts of the Little Giant - is a versatile pumping units used for drainage of industrial and domestic waste water, fluid handling to wastewater treatment plants, pumping out rain and surface water. With a special one-piece design with different types of impellers, Little Giant pumps can pump liquids containing higher amount of abrasive and fiber components.

Little Giant Co. has produced the first models of pumping equipment in 1989, and, as evidenced by positive feedback from consumers, the use Little Giant Effluent Pumps leads to an increase in productivity pumping stations with a significant decrease in the cost of their care. Moreover, the effectiveness of sanitation increases not only the replacement of obsolete units, but also during the installation of pumping equipment series Little Giant Sewage Pumps instead of modern foreign-made pumps.

Among the large selection available on the market of imported plumbing pumps, and many are indeed examples of high-end technology. That's just the level of their suitability for use in the Russian conditions is extremely low so that it is almost always expensive equipment operate smoothly for a long time and at the proper level.

Broken snail, broken impellers, a burned-out pump rotor, worn hydraulics or ongoing mechanical seals - fairly common types of injuries Grundfos pumps, after a short service at the local water utility companies. Very often, the discrepancy of sewer systems to European standards, regulations, specifications, etc. is the reason for denial of service centers to repair the pump. And all that remains is the owner of a failed pump - is the purchase and installation of spare parts, often at a cost of only slightly inferior to the new unit. And in those rare cases where all conditions of operation can be aligned to the required standards and in the presence of all necessary additional equipment, such as the shield of automatic control, maintenance of imported pump still leaves a lot of money.

The reason is the high costs and the price of bearings, mechanical seals, gaskets and other, requiring the timely replacement of parts, and that the installation, repair and maintenance of Grundfos pumps must be carried out by experienced qualified professionals, whose content the state enterprises are also expensive. It turns out that the purchase of imported plumbing pump - just the beginning in a series of upcoming expenses.

That's why today is such a popular low-cost domestic pumps, among which pumps Little Giant highlighted a number of its advantages. Compared with pumps from other Russian producers, such as pumps Circulator Pumps, Transfer Pumps, Condensate Pumps not afraid of flooding - very common in sewers. Besides pumps "Little Giant" structurally suited to automation, which greatly simplifies their maintenance. Which can not be said of most domestic units, to control the operation of which requires the presence of the operator and periodic adjustments and debugging equipment.

Moreover, the inability to automate starting the engine to open the valve inevitably leads to water hammer every time you start and stop the pump, and the lack of an automatic fluid level check - to the rapid deterioration of the impellers, check valves, gate valves, pressure gauges, coupling, pipeline.

Avoid these problems and allows the equipment pump control panels, through which plumbing units Little Giant is a complex automated, self-oriented in a liquid that can track and maintain the water level at a given value. Self-diagnostic system monitors the pump pump rotor windings changes in temperature, humidity degree of isolation and, in case of deviation from the allowable loads and to detect leaks, displays the data on the bulletin board. Ease of operation of pumps Irtysh is also achieved through plug-type connections, allowing quick and easy enough to dismantle the unit for maintenance and set it back in line.

Summing up the above, it should be noted the following advantages, which ensures operation of plumbing pump Irtysh:
1. The small cost to purchase the pump.
2. Reduce operational and maintenance costs.
3. Reduce time spent on maintenance.
4. Compactness of the single-warhead Little Giant Sump Pumps to reduce the volume of construction of sewerage systems.
5. The process of pumping effluent becomes completely automated. There is no risk of accidental flooding.
6. Increased energy efficiency pumping stations: first, due to optimally matched equipment, and secondly, due to improved flow-through unit.
7. The broad scope - from pumping rainwater to the pumping of clean water.
8. Environmentally friendly use of running Little Giant Utility Pumps provided a low level of noise, vibration and the lack of heat.
9. Possibility to order the pump with the necessary operating parameters corresponding to specific technical requirements.
10. Finally, the Little Giant Submersible Pumps - a modern high-performance, high quality and reliable equipment, adapted to work in the USA context.

Circulating pump: Types of installation

Permissible mounting methods

• In-line pumps are designed for horizontal and vertical mounting directly to the plumbing pipeline.
• To remove the pump rotor, the pump elements is sufficient space.
• When connecting the plumbing pipeline to the pump should not be given voltage and weight plumbing pipeline, a pump must be installed on the support (if any).

Improper installation

• Installation at which the pump rotor and terminal box facing down, is not allowed.
• If the power of the engine exceeds a certain level, before installing the pump in a horizontal position should consult with the manufacturer.

Circulating Pump Installation

In installations where the level of fluid intake is below the axis of the circulator pump used to fill in two ways:
1) in aggregates of a small filing with the diameter of the suction pipe of 250 mm at the end of her under the water level have a foot valve. In this case, make the filling through a funnel and a crane at the top of the pump casing from the PEX Plumbing system or special filler tank;
2) in the aggregates with d> 250 mm receiving valves do not put produce and fill with suction air from the pump is a special expansion pump (commonly used types of Grundfos pumps and Taco, creating a expansion to 97%).

If there is contamination of the liquid intake funnel on the suction tube is combined with a slit or a strainer. Control over the operation of the pump is over the testimony of the gauge and pressure gauge attached to the suction by the discharge nozzle, flow measurement is made on the flow-meter mounted in the pump discharge line.

So how about a load of the pump can be measured by manometer readings, are often reluctant to install meters on each pump and have a meter on the common plumbing pipeline, controlling for his testimony filing unit as a whole. As the flow meters are used diaphragms, Venturi tubes and wing water meters. Power expended by the unit, is determined by the voltmeter, ammeter or wattmeter, disposable on an Taco board assembly cli install.

To start the pumping unit should produce preliminary tasks: to ensure free rotation of the shaft, check the tap and manometer gauge, fill pump and suction pipe, open the flow of cooling water into the bearings (in units with a cooled bearings), to check the position of the oil in the bearings (at bearings lubricated). Valve on the discharge plumbing pipeline Circulating pump during start-up must be closed (for n <250 br="">

Start the pump is as follows: turn on the motor and speed it is brought to normal, slowly open valve on the pump discharge nozzle to achieve the required filing date; open valves that lead to the cooling water pump seal. When the pump should monitor the temperature of the bearings and the motor housing, which under normal circumstances should not exceed 60 ° C, the presence of oil in the chamber bearing (with oil lubrication), the density of glands (tightening of the packing is considered normal if he misses a few drops of water and temperature it is low).

Stop pumping unit is closing the valves on the discharge pipe, turn off the engine, close the valve on the suction tube and the cooling off seals and bearings). Start, the service at work and stop assemblies considerable power necessarily governed by special instructions. Special instructions subject to the exploitation of nutrient pumping units of steam boilers and pumps for hot liquids.

With modern technology development of automatic process control automation of pumping units is not difficult. Automatic pump control provides the following operations:
1) preparation of pumps to start, is to monitor the position of valves and pumps filled with liquid;
2) starting and stopping of pumps depending on the flow required by customers;
3) Stop the pump at fault it and start another pump to replace a faulty;
4) protection against overheating, seals and bearings;
5) the protection of hydraulic pumps, it becomes impossible to start the pump, not filled with fluid.
In developing the scheme of automation and protection of pumps may be provided for the necessity of pumping unit for the intended program. Automation improves the efficiency and reliability of the pumping unit, reduces the number of attendants.
