Every Application has a Solution with Thaman Rubber Pumps

Reliable and Versatile Air-Operated Diaphragm Pumps for Every Application

Thaman Rubber Co. is proud to offer a diverse range of air-operated diaphragm pumps, designed to tackle a variety of pumping applications. Our diaphragm pumps are available in both metallic and non-metallic materials, with port sizes ranging from 3/8” to 2”. With flow rates spanning from 10 GPM to 145 GPM, they

are perfect for handling tasks of all scales.

Our pumps feature an innovative unbalanced air valve design, preventing the valve from remaining in a centered position and eliminating pump stall-out, even at low inlet pressures. This makes them reliable and efficient, no matter the challenge. Diaphragm pumps are suitable for an array of uses, including pumping solvents, chemicals, coatings, inks, soaps, degreasers, machining coolants, and wastewater treatment additives—just to name a few!

In addition to providing premium pumps, Thaman Rubber Co. specializes in repair and rebuild services. For each size and style of diaphragm pump, we offer specific air motor and fluid section repair kits, saving you time and effort by eliminating the need to order parts individually.

Lubrication Equipment for Every Need

Our lineup doesn’t end with diaphragm pumps—we also supply high-quality air-operated lubrication pumping equipment. Whether you’re looking for a compact 35-gallon portable lubricator pump or a robust 2-foot ram setup for a 55-gallon drum of grease, Thaman Rubber has you covered.

Ideal for pumping materials such as motor oils, gear oils, track roll spindle lubricants, and heavy-velocity greases, our lubrication equipment is complemented by metered and non-metered fluid control handles to suit your specific requirements.

Streamline Your Operations with High-Pressure Hose Reels

To further enhance your setup, we offer a line of high-pressure hose reels. These reels securely store your high-pressure lubrication lines, keeping them off the floor to prevent accidental damage and costly spills.

Vertical Turbine Pumps: Their Benefits & How Submersible Pumps Compare

Vertical Turbine Pumps (VTP) and Submersible Pumps are widely used across industries for liquid transfer—but why choose one over the other? Some decisions are straightforward, while others require deeper evaluation.

Understanding the Basics

VTPs function as multistage centrifugal pumps, typically designed with a motor positioned above a discharge head, with the assembly extending into the water below. The motor drives a long shaft reaching the depth of the pump assembly, starting with a screened bell at the base, leading to suction bowls containing impellers. These impellers connect through the column assembly up to the discharge head. Their number and size vary based on required head (lift + friction resistance) and flow rate (Q)A submersible pump is a complete unit containing the motor, impeller, discharge  and screen.  Given their name, no surprise completely submerged in the liquid being conveyed which in turn is used to cool the pump.

Submersible pumps, on the other hand, are self-contained units housing the motor, impeller, discharge, and intake screen—all fully submerged in the liquid they pump. Their design allows the surrounding liquid to cool the pump during operation.

Key Differences & Applications

• VTPs are ideal for high-flow, high-head operations, commonly used for clean water applications. They require infrastructure—such as floating platforms or docks—but offer lower long-term maintenance costs. While they can handle some water level fluctuations, they are less effective when dealing with slurry, often requiring sump dredging.
• Submersible pumps provide greater flexibility in application and location. They come in varying sizes and capacities but are tailored to specific liquids and have a limited range of flow and head capacity. While easier to move and install, their maintenance costs can be higher relative to initial investment.

Making the Right Choice

Both pump types offer unique advantages depending on operational needs. VTPs excel in high-volume, high-lift applications, making them ideal for larger-scale systems. Submersible pumps, meanwhile, provide cost-effective installation and adaptability for low to medium-flow applications.

When selecting a pump, consider key factors such as Total Dynamic Head (TDH), flow rate (Q), liquid density, accessibility, liquid depth, and long-term maintenance requirements. Understanding these elements ensures an efficient pump selection that meets performance needs seamlessly, maximizing reliability and operational efficiency.
