summary
The 2SK series of water ring vacuum pumps is essentially two SK series pumps connected in series. The SK series pump can only achieve a vacuum degree of -700mmHg, so the 2SK series was developed to achieve higher vacuum levels and greater pumping rates. However, with the introduction of the energy-efficient 2BV and 2BE1 series, the 2SK series will gradually be replaced in many applications. While the 2SK-P1 series pump works well in the 10-50mmHg range, its efficiency is lower in high vacuum areas. For long-term operation in high vacuum areas, it is recommended to use a Roots+water ring vacuum unit to achieve optimal air extraction efficiency.

Note:
1. The performance indexes and performance curves listed in the table are measured under the following specified conditions,
◆ The atmospheric pressure is 0.101325MPa (760mmHg)
◆ Inlet water temperature 15 ℃
◆ Suction air temperature 20 ℃
◆ Relative air humidity 70%
2. The water supply is the value when the suction pressure is -0.05MPa (- 400mmHg), and it can be greater than this value when the vacuum limit is reached.
3. Performance tolerance ± 10%
Application Area
The 2SK series water ring vacuum pump or unit can be used to extract air or other insoluble, non water Gas containing solid particles and non corrosive. Widely used in machinery, petrochemicals, pharmaceuticals Food, sugar industry, and electronics.
Product advantages and characteristics
Mechanical seal structure, compact structure, easy disassembly, simple maintenance, and stable performance
National standard motor with strong power. Copper wire with multiple turns, strong overload resistance, energy-saving and energy-saving
The pump body is made of thickened cast iron, with reliable quality, smooth operation, low noise, and self suction ability
It can be connected in series to form a unit, and the 2SK-P1 series two-stage water ring vacuum pump is equipped with an air pump at the suction port, which still has a relatively high pumping speed
The main characteristics of the 2SK two-stage water ring vacuum pump are:
● Compared to single-stage water ring vacuum pumps, they have the characteristics of high vacuum degree and large pumping speed in high vacuum areas;
● Compact structure and easy maintenance;
● Widely applicable, it can extract various gases containing water vapor, flammable, explosive, small amounts of dust, and small amounts of liquid;
● Mainly using water as the working medium, with low maintenance costs;
● Can work in harsh environments.
Factory Shooting
Workshop shooting, complete equipment, and rich production experience
