CONSTRUCTION:

Pumps of type WL and WLs are centrifugal, single-stage vertical impeller pumps driven by a 50 Hz or 60 Hz electric alternating current motor. The electric drive is transmitted by an inseparable flexible coupling. The pump body is divided along a vertical plane. The pump’s flanges are of the same diameter, located at the same height in relation to the pump base.The shaft with rolling bearings is sealed in the stuffing-box by one mechanical seal. The pump construction enables its easy disassembling without motor and pipe connections dismounting.The WL pump is not capable of sucking the liquid itself. WLs pumps are equipped in a vacuum pump Pa and can operate as self-suction pumps.

Considering the material used for the pump’s casing and stuffing-box there are two versions of pumps:

• type M – material: grey cast iron;
• type T – material: bronze.

PUMPED MEDIUM:

Pumps WL and WLs are suitable to pump the following mediums: fresh water, sea water and oil of viscosity up to 5°E (36,2cSt).

Other liquids can be also pumped when agreed with manufacturer.

The maximum temperature of pumped medium:

- fresh water and oil – up to 95°C (368 K),

- sea water – up to 45°C (318 K).

APPLICATION:

In shipbuilding:

• sea and fresh water cooling systems,
• bilge systems,
• ballast systems,
• fire-fighting systems.

In land execution:

• stationary fire-fighting systems,
• public and industrial water supply,
• power industry.
