FAQ
What does the relief valve do on the 30UR-BMS pump?
The built-in relief valve helps protect the pump and connected systems from excessive pressure by redirecting flow when pressure exceeds the preset limit.
Is the Haight 30UR-BMS self-priming?
Yes. The pump is designed with self-priming capability, making it suitable for demanding industrial transfer applications.
What fluids can this pump handle?
The 30UR-BMS is commonly used with lubricating oils, hydraulic fluids, petroleum products, light chemicals, inks, soaps, and other compatible industrial liquids.
What is the advantage of an internal gear pump design?
Internal gear pumps provide smooth, pulse-free flow with excellent suction capability and efficient handling of both low and medium viscosity fluids.
Can the pump operate in either direction?
Yes. The pump can operate in either rotational direction, although the relief valve must be configured properly for the intended rotation.
Is this pump suitable for continuous industrial operation?
Yes. The durable ductile iron construction and heavy-duty internal components make it ideal for continuous-duty industrial applications.
Does the pump include a motor?
No. The 30UR-BMS is supplied as a pump end only and is intended for integration with a compatible motor assembly.
