Non-metallic mechanical seal centrifugal pumps with open impeller

 

ALPHADYNAMIC PUMPS (UK) Ltd manufactured resin-encased horizontal plastic centrifugal pumps operated by a direct-drive motor (max 3000 rpm) for fast fluid transfer and  with flow rates ranging from 6 to 75 m³/h. Their special open-impeller design allows pumping even with very dirty liquids having apparent viscosity up to 500 cps (at 20°C) and small suspended solids. There are two versions available with different internal mechanical seal depending on use, A (lip seal) and B (bellows seal).

 

Main Features
- Available in polypropylene, PVDF
- Positive suction head operation
- Mechanical bellows or lip seal
- Usable even with extremely dirty liquids
- Flow rates: from 6 to 75 m3 /h
- Head: up to 38 mt
- Quick and easy maintenance
- Economical spares.
- Viscosity: up to 500 cps
- Upon request the pump can be supplied with flanges

 

Motors:
IP55 - F Class - 2-pole - 50 Hz - three-phase
Single phase from 0,55 kw to 2,2 kw - 50/60 Hz

 

Max. operating temperature:
PP: 65°C
PVDF: 95°C
How it works
The impeller is integral with the shaſt and direct-drive electric motor and is rotated at a preset speed with the centrifugal effect producing suction on the intake side and discharge on the delivery side.

 

Description of the Pump
Resin-encased horizontal centrifugal pumps feature a solid pump casing and a lantern for connecting the electric motor and inspection of the mechanical seal. The open impeller is fitted to the pump shaſt that is integral with the drive shaſt of the electric motor. The shaſt mechanical seal is housed at the rear of the impeller.

Installation
ADH horizontal centrifugal pumps should be installed with the shaſt positioned horizontally in a positive suction head arrangement. Suitable devices should be fitted to prevent dry running and the formation of a vortex and possible air suction. ADH horizontal centrifugal pumps should only operate whilst filled. Running dry or with bubbles can cause damage to the mechanical seal.
