AH Series: Heavy-Duty Slurry Pumps
AH pump is cantilever, horizontal centrifugal slurry pump.It mainly applied to metallurgical, mining, coal,
power, building materials industry conveying strong abrasion, high concentration of slurry. This type of
pump can use multi-level series.
AH pump with Replaceable wear metal liner or rubber lining,impeller applied wear-resistant metal or rubber
materials.The inner and the impeller of the HH pump only use wear-resistant metal.
The shaft seal of the AH pump can use Packing seal or centrifugal seal.According to requirement the spit
export position can be 45 degree angle space,rotate eight different angles to installation.
Dimensionally interchangeable with Sinofine AH Series pumps
For the past half-century end-suction, split-case, centrifugal slurry pumps have set the world standard for
heavy duty abrasive pumping applications. With large shaft diameters, heavy duty bearing assemblies
and robust slurry pumping capacity, Sinofine Slurry pumps provide a cost-effective and ideal alternative to
longer lead times and engineering services that are often costly or not available elsewhere.
Application customization comes standard with this line using a variety of metallurgic and elastomeric
parts options, an assortment of seal arrangements, and a standard impeller adjustment mechanism
incorporated into every base/assembly.
S Series Profile:
· Discharge Diameters 25mm to 450mm
· Heads through 240ft (73m)
· Flow Rates through 22,000gpm (5,000m3/h)
· Casing Pressure Tolerance 300psig (2,020kPa)
AH Series Features:
WETTED PARTS
o IMPELLERS– wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable)
– pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in
preventing seal contamination – optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on
certain sizes) offer wider hydraulic options in single sizes
o LINERS – wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) –
active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue
o THROATBUSH – wide variety of metallurgic and elastomeric options (metal and elastomer
interchangeable) – adjustable via cotters to account for wear over time and increase efficiency
o CHEMICAL COMPATIBILITY – operating pH range from 3 to 14 – especially corrosive chemicals handled
using diverse variety of elastomeric wetted parts
· SEALS– Sinofine offers a wide variety of seal options to suit any process requirements
o EXPELLER (CENTRIFUGAL SEAL) – available with low flow water flush or zero flow (grease lubricated)
options to provide exceptional sealing where water introduction to the seal is intolerable or limited
o STUFFING BOX – gland sealing with packing and lantern ring
o Sinofine LOW-FLOW SEAL – Sinofine offers a variety of low-flow seals, which can significantly reduce
water usage in the stuffing box – the low-flow seal systems can be applied in a variety of applications using
several material and component options
· BEARING ASSEMBLY – all bearings assembled with highest quality tapered roller bearings in controlled
environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced
overhang in the wet end contribute to long life and reliability in the field
· CASING – split-case design allows for ease of access and maintenance on wet end parts – cast
ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time
· BASE – a single piece base with integrated adjustment mechanism for impeller clearance within pump
– bearing assembly locks into base using four heavy-duty bolts – three custom designed mounting modes
available: overhead using integrated single pedestal system, side-by-side with adjustable motor mount, and
direct-coupled with precision in-house alignment (optional VFD packages available)
