Torque Flow Pumps

Smooth extra heavy section designed for unobstructed free flow. Abrasive or solids-laden flow goes directly into vortex of liquid and out the discharge. No close clearances between casing and impeller (as in conventional pumps) to generate wear. Nothing between suction and discharge to jam, clog, break or bind... a totally non-clog concept in pumping.

Impeller, fully recessed out of flow path, is not subjected to wear by solids or abrasive particles churning in the flow when handling solids or slurrie greatly improving impeller life. Impellers may be threaded to shaft to provide shaft end protection.
Shaft :

Heavy duty shafts are designed for maximum operational heads and low deflection and vibration. 
Shaft Sleeve:

Shaft sleeve is keyed to shaft and gasket sealed to stop leakage under sleeve.
Stuffing Box:

Designed for gland packed arrangement fitted with neck bush and has been provided with external fluid sealing connections which enhances life of gland packing. Mechanical seals can also be provided.
Bearings:

Angular contact ball thrust bearings carry radial and thrust loads. Thrust bearings are back to back mounted, locked with nuts and lock washers. Oil lubrication is standard. Constant level oiler maintains proper oil level. Bearings are well protected from dirt. Grease lubrication can also be provided. 
Exclusive Advantages
Free Passage :

The recessing of the T.F. Pump impeller permits unobstructed passage through the pump casing.
Non-clogging :

Solids up to the full diameter size of the discharge connection can pass through the pump without danger of clogging. Also long fibrous materials will cause no problems.
Long Life :

The robust and simple design as well as the correct materials for the job guarantee long service life. 
Simple Design:

The simple open and concentric design guarantees a trouble free service even under extreme conditions.
Wear Resistant:

The new T. F. Pump casing (axiaspiral) ensures that the solids entertained in the flow are quickly discharged from the pump and thereby reducing abrasion.
Low Maintenance:

More than 20 years experience in production and application of T.F. Pumps has shown that the Torque Flow Pumps need less spares than any comparable solids handling pumps. 
Construction Material

The materials of construction are indicated as an example of generally accepted practice, but are not intended as recommendations of fitness for a particular purpose. The customer must determine and take the ultimate responsibility for specifying the proper materials to handle the particular fluid pumped. Unless otherwise specified, all pumps shall be furnished with the standard fitted materials to meet the system requirement.
