Product Description
3/2C-AH is a centrifugal slurry pump, which is a Warman type of slurry pump. The pumps are designed in heavy duty working performance, in order to handle high abrasive density slurries. AH Warman slurry pumps are horizontal models, with high chrome material to slurry pump wearing parts, including slurry pump impeller, volute liner, throabush, frame plate liner insert.
3/2 C-AH slurry pumps are 3 inch suction, 2 inch discharge, therefore, 3/2C-AH pumps are also called 2 inch slurry pump. A rotating slurry pump impeller in AH slurry pump is creating centrifual forces, which can pump the slurries into a certain distance. This slurry pump is designed with excellent wearing life to high chrome material using in wearing parts, and high efficiency is featured by a closed type of impeller.
AH slurry pumps are metal lined type of slurry pump, the slurry pump parts including impeller, volute liner and frame plate liner can be changed to rubber lined material, which is the AHR type of slurry pump.
3/2 C-AH slurry pumps are used for slurry pumping, the slurries are normally contain solid, ash, mineral aggregate, slurry pumps can transfer 60% solid by weight. The slurry pumps can also used for transferring sand, therefore, slurry pumps are also called as sludge pump and sand pump.
In different working environment, horizontal slurry pumps are highly used in mineral processing, coal preparation, filter press feed, cyclone, aggregate processing, Copper concentrator, gold concentrator, iron concentrator, primary mill grinding, slurry pumping to tailings, secondary grinding, industrial slurry processing, power plant ash pumping, food processing, sand dredging, booster sand piping, ash handling etc.
1. 3/2C-AH is designed with long wearing life in order to reduce operation costs.
2. 2 inch slurry pumps are designed with 3 inch suction, 2 inch discharge.
3. Closed impeller designed with high efficiency, in order to reduce power consumption.
4. Large diameter can achieve high working pressure, whereas lower the rotating speed and extend the wearing life.
5. Large particle pass ability can working with sand, gravel, ash.
6. Horizontal slurry pumps are designed with 60% solid percentage by weight.
7. Warman slurry pumps AH model can be driven with motor in ways of ZVz, CRz, CV, DC.
8. Slurry pumps are exchangeable with metal lined pumps and rubber lined parts to AHR type of slurry pump.
9. Strong heavy duty design on base and shaft can stand Max. shaft power.
10. Variable selection deisgn on seals of slurry pumps, includes expeller seal, gland seal and mechanical seal.

7. 3/2C-AH slurry pump Capacity is from 21.6 to 88 m³/h.
8. Working pressure to 3/2C-AH Weir slurry pump is from 13 to 62.7 meters.
3/2C-AH Slurry pump wearing parts include impeller, volute liner and frame plate liner insert.
Impeller - Slurry pumps impeller are designed with high chrome material, rubber lined material, elastomer material, A05, A07, the impellers can also be customized to SS304, SS316, SiC materials. More than that, when we talk about 3/2C-AH, the standard material is high chrome A05 material.
Volute liner - The volute liner of slurry pumps are inside of frame plate and cover plate, and outside of the impeller, the volute liner is also standard as high chrome A05 material because of it is the wearing part of the slurry pump.
Frame plate liner insert - Comparing with frame plate, the liner insert is working along with the slurry, therefore, the frame plate liner insert to 3/2 AH Weir pump is also designed with wearing characters.

Gland Seal
Gland seal is the most common used seal to Warman slurry pump, the gland packing seal is designed with clean water injection into the packing, the clean water is required a certain of pressure, and the pressure is normally larger than the pump working pressure, for example: when 3/2C-AH slurry pump is working at 25 meters, the injected clear water is normally required ＞2.5 bar, in order to push the slurry back to the pump body, and the injected clear water is pumped out of the pump with the slurry.
Expeller Seal
The design of expeller in slurry pump is to create pressure against impeller forces, in another word, the expeller can also create a centrifugal pressure, the pressure is to against the pressure of slurry pump. The advantages of expeller seal: 1. slurry pump doesn't require too much pressure on clean water injection; 2. slurry pump expeller seal can inject grease oil when gland water can't be provided, 3. without too much pressure, the packing of slurry pump can work longer life.
Mechanical Seal
Mechanical seals of slurry pump is designed with no leaking features, which are highly used for chemical, food, power plant, steel plant, aluminum plant etc. The material of mechanical seals end face is SiC, in order to achieve long wearing life, and water injection is required to cooling the heat, however, one thing must pay attention, when the slurry pumps are using the mechanical seal, water injection must open before the slurry pump turn on, more than that, the slurry pumps must stop in advance of the water injection.
Slurry pumps are designed with three types, horizontal slurry pumps, vertical slurry pumps, submersible slurry pumps.
Horizontal slurry pumps: the "horizontal slurry pump" refers to the pump whose shaft is parallel to the horizontal plane. The type of horizontal slurry pump include models of: AH heavy duty slurry pump, HH high head slurry pump, ZJ high efficiency slurry pump, L light duty slurry pump, G slurry gravel pump, AHR rubber lined slurry pump.
Vertical slurry pump: comparing with "horizontal slurry pump" the vertical slurry pump shaft is parallel to the vertical plane, where the slurry pump parts: impeller, volute liner and frame plate liner are on the bottome of the slurry pump. The type pf vertical slurry pump include models of: SP centrifugal vertical slurry pump, SPR rubber lined vertical slurry pump, ZJL high efficiency vertical slurry pump.
Submersible slurry pump: submersible slurry pump are designed with agitator on the bottom of the slurry pumps, and the same purpose of use for submersible slurry pump and vertical pump are pumps are used for pit, where the slurry is below slurry pump central level, however, when the depth of slurry is larger than 5 meters, as slurry pump manufacturer, submersible slurry pumps are normally suggested. The type of submersible include models of: HY hydraulic submersible slurry pump, and EL electric submersible slurry pump.
The capacity of slurry pump is also named as flow of slurry pump, the slurry pump capacity include: solid, water, ash, Mineral material, Chemicals etc, the Units of measurement to capacity of slurry pump can be: m³/h, L/S, GPM, T/H. The capacity of slurry pump can be calculated
Volume capacity (Q) = average flow velocity (v) x pipe cross-sectional area (A).
Mass capacity rate (M) = medium density (ρ) × volume flow rate (Q) = medium density (ρ) × average flow velocity (v) × pipe cross-sectional area (A)
Pipe capacity:
(1) Capacity rate (instantaneous flow rate) = pipe cross-sectional area ⅹ flow rate.
(2) Capacity rate (hourly flow rate) = 3600 x pipe cross-sectional area x flow rate.
