Weir Minerals provides a wealth of information on Warman pump curves. Warman pump curves can be difficult to navigate if you are not familiar with them. All of the Warman pump curves are laid out the same.
The company is the world’s best warman high pressure pump replacement supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Information and the location of the information on a Warman pump curve can be seen on the included images, and is described below.
Located at the top is the pump size and model: In the example we are using a Warman 6×4 pump, model AH and WRT design. WRT stands for wear reduction technology.
In the upper right-hand corner is the pump suction and discharge size. The size refers to the pump suction and discharge inside diameter.
The impeller information is located below the suction and discharge information. You will find the number of vanes, impeller diameter, impeller type, part number and material. In the example below, the impeller has 4 vanes with a 15.2” diameter. The impeller is a closed design versus an open design and is metal (high chrome iron).
Below the impeller information on the right hand side is information on the available bearing assemblies for that Warman pump size and model. For example: A Warman 6×4 EAH pump has a “E” size bearing assembly which is designed for a maximum installed horse power of 161.
The next item is the seal type. The example curve has a pump with a standard packed gland. Warman pumps are available with many different seal arrangements. The most common are packed, expeller, and mechanical seal.
Liner material maximum design speed. The maximum design speed is based on the material point of failure. Weir Minerals does not recommend exceeding the design speeds.
Minimum passage size. The description is a little misleading. You have to look at it from the pump’s point of view. This is referring to the smallest internal pump dimension. The example below the smallest internal dimension for a 6×4 AH pump with a E4145WRT1 impeller is 1.61”
The flow rate is located at the bottom of the page. The units are gallon per minute.
The head is located on the left side of the page. The units are in feet of head.
The pump speed is located on the left side of the page. Slurry pump curves are different from ANSI pump curves. ANSI pump curves normally have a set speed and vary the impeller diameter. Slurry pump curves have a set impeller diameter and vary the pump speed.
Pump efficiency is located at the top of the curve. The red efficiency line is known as best efficiency point or BEP. The Warman 6×4 AH example curve has BEP of 72%.
NPSHr or net positive suction head is located towards the bottom of the curve. We recommend that NPSHr be at least 2 ft higher than NPSHa, otherwise the pump will cavitate.

Tobee® TH Slurry pumps are interchangeable with world’s standard Warman AH slurry pumps for heavy duties, A wide variety of impellers and shaft seals provide a perfect fit for a wide range of applications. The TH slurry pump provides excellent wear life while maintaining efficiency during the wear cycle providing the best total operating cost. These horizontal slurry pumps are designed for hyper heavy duty applications such as mill discharge, process plant, coal washing, dregding sands, tailings and high pressure pipelines, as well as other specialty applications.
Design Features:
• Bearing assembly - a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
• Liners - easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintenance. Hard metal liners are completely interchangeable with pressure moulded elastomer.
• Elastomer seal rings back all liner joints.
• Casing - Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
• Impeller - front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and moulded elastomer impellers are completely interchangeable.
• Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
• Throatbush - wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
• One-piece frame - a very robust one-piece frame cradles the cartridge type bearing and shaft assembly.
• An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance
