☑ The seal has several different designs depending on the conditions of the pump operation: 1) without cooling and hydraulic lock, 2) with water cooling if operation temperature is above 120°C, 3) with hydraulic lock to prevent the ingress of oxygen into the pump while operating in a vacuum.

☑ Radial displaceability of stuffing box on the balls allows her to become self-aligning coaxially with the shaft (within 1mm or 1.5 mm to the side) as well - automatically compensate radial vibrations of the shaft (up to 0,5 mm on the side).

☑ Gland packing is from braid thermally expanded graphite. Rubber O-rings are made of rubber compound with high heat resistance in the water.

☑ Produced from corrosion-resistant steel of 420 (AISI) or 321H (AISI), of bearing balls is A473 (AISI). The warranty period for the device - 4 years.

☑ The sealing devices for horizontal and vertical condensate pumps of various brands operate at thermal power plants, at heat and power plants and at nuclear power plants.

☑ The seals are produced only in the version with the intake of cooling water to the seal housing or inside the pump, because the temperature on the suction pipe can reach 160°C.

☑ Automatic centering stuffing-box (up to 1 mm per side) can be tracking of even the minimum of the radial oscillations of a rotating shaft (no more than 0.5 mm on the radius), so this reduces the load on the packing, ensuring reliable operation of equipment.

☑ Gland packing is from braid thermally expanded graphite. Rubber O-rings are made of rubber compound with high heat resistance.

☑ Material of metal parts of seal is corrosion-resistant steel grade of 420 (AISI) or 321H (AISI), of bearing balls is A473 (AISI). The warranty period for the device is 4 years.

☑ Sealing devices are available in an assembly and include protective sleeves of the shaft. Any pump modifications are not required.

☑ The seals for PE and PD pumps has a long experience in operating at heat and power plants and metallurgical plants.

☑ The mobility of stuffing box in the sealing device provides the dynamic compensation of the radial oscillations of rotating shaft (up to 0.5mm on the radius) and the possibility of static self-aligning (limited of 1mm or 1.5 mm on the radius).

☑ There are two versions: 1) the device housing with cooling if operating temperature exceeds 120°C and 2) without cooling - at lower temperatures. In any case, the cooling water to the lantern ring is not required.

☑ As a soft gland packing the device uses braided thermally expanded graphite. Rubber O-rings are made of rubber compound with high heat resistance in the water.

☑ The material of metal parts of seal is corrosion-resistant steel grade of 321 (AISI), of bearing balls is A473 (AISI). The warranty period for the device is 4 years.

☑ The sealing device is available as an assembly unit and does not require any modification of the pump.

☑ The seal operates at thermal and nuclear power plants, at district heating networks for the pumps pumping heating water over the network, and for pumps often used as a recirculation pumps.

Kiev enterprise "Energotehnika" develops, manufactures and sells sealing devices with a self-centering stuffing box for many types of industrial equipment.

This page contains descriptions of self-centering seals for district heating network pumps type of SE, boiler feeding pumps type of PE, booster pumps PD, condensate horizontal pumps type of Ks, KsD and condensate vertical pumps KsV, KsVA series.

Pumping equipment of these types is made at the following factories:

◎ NASOSENERGOMASH Sumy JSC ( SE, PE, PD, KsV, KsVA, Ks, KsD pumps);

◎ "Yuzhgidromash" Berdyansk (PE pumps).
