Open Hopper Pumps
 |
seepex pumps
of group T are used to transport viscous or concentrated products.
They utilize a feed hopper and an auger feed screw to improve product
feed.
Depending on viscosity and fluid characteristics, the optimum solution for your application can be selected from six ranges |
Range
BTI 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| highly viscous
or compacted products which tend to bridge metered addition of
additives dewatered sludge
with or without lime addition 18-45 % DS, paper stock 10-15 % DS,
spent grain, paste and meat (large pieces |
bridge breaker
/ mixing device with two counter rotating phased paddle shafts and
dedicated variable speed drive enhanced filling of conveying elements through cylindrical / conical compression zone universal joint sleeve protection |
rectangular
length modifiable removable compression housing for service work (standard)
|
pitch and diameter adapted to the operating conditions for optimum product feeding |
Range BTE 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| Highly viscous
or concentrated, crumbled products which do not tend to bridge dewatered sludges
|
optimum filling
of conveying elements through cylindrical compression zone with enlarged diameter housing and feed screw |
rectangular
enlarged diameter length modifiable removable compression
|
increased pitch
and diameter for optimum product feeding
ribbon screw
|
Range BT 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| highly viscous
products without / with poor flow characteristics
thickened sludges
|
optimum filling of conveying elements through cylindrical / conical compression zone | Rectangular
length modifiable removable compression housing for service work (option) |
pitch and diameter adapted to the operating conditions, for optimum product feeding |
Range BTM 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| Fruit, vegetable
and meat processing, juice production, starch production potatoes, apples, pears, onions, carrots, fish, chicken |
maceration and
pumping of whole fruits and vegetables (partially in lumps)
seepex patent 3833515.8-23 closed system, oxidation/discolouring of the conveying product is prevented |
Rectangular
length modifiable extended compression housing with stationary cutting elements, easily repaired |
extended, with rotary knives in the area of the cylindrical compression zone |
Range BTQ 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| medium to highly
viscous products with poor flow characteristics
thickened sludges
|
length
identical to pump of group N
(suction casing/feed hopper exchangeable) |
square
inspection covers on both sides (standard) |
coupling rod in standard design, with short screw for easier feed |
Range BTES 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
| highly viscous
and concentrated products
dewatered sludges
mash, paste and meat (large pieces) |
optimum filling
of conveying elements through cylindrical compression zone with enlarged
diameter
end cylinder / screen for a simple and quick replacement of rotor and stator without disassembly from silo |
Rectangular
enlarged diameter length modifiable removable compression housing for service work (standard)
|
increased pitch
and diameter for optimum product feeding
ribbon screw for high DS contents and adhesive products |
Ranges TINS, TENS,
TNS, TMNS, TQNS 
| Typical Applications | Technical Features | Feed Hopper | Auger Feed Screw |
|
The wet-end of the ranges TINS, TENS, TNS, TMNS, TQNS are identical to the ranges BTI, BTE, BT, BTM, BTQ illustrated on this page. These ranges have their own bearing casing with free bareshaft and are used when the customer wants a separate foot-mounted drive |
