Case Study: Chemical causing diaphragms in pump to rupture.

Case Studies

The R. A. Ross team knowledge of pumps and chemical issues solves crystallization problem.

Situation: A well known drywall manufacturer in southern Indiana was having an issue with an air operated diaphragm pump which was being used to inject a dispersant chemical into the wallboard fabrication process. The issue with the diaphragm pump was that the dispersant had a tendency to set up and “crystallize” in the pump and cause the diaphragms to rupture.

Lobee stainless steel gear pump model 2LOE w/ ¼-HP, 1150 RPM motor: Operating a 3 GPM @ 45’ TDH, ambient temp.

Solution: We recommended a small stainless steel Lobee gear pump that would hold less product in the pump and had the capability to shear any crystals that may have been formed in the liquid while the pump was not running.

The customer has been very pleased with the result and the pump has been in operation for approximately 3 years.

Tough applications and regulations are right up our alley

Situation: When a rural sewer utility came to us looking for a more economical grinder pump for their sewage lift stations, we had the exact solution; the HCP, GF Series grinder pump which was a “drop in” replacement for the competitors pump the customer had been using. In addition to matched performance and ease of installation, the HCP pump was over $500 less expensive than the competition. The customer is so satisfied with the price and performance of the HCP pumps, they are replacing the competitors pumps one by one as they go bad. The first HCP pump installed has been running for two years now with no issues. HCP Pumps America manufactures a wide range of submersible pumps from fractional HP to 250-HP for just about any dewatering or sewage application.

The HCP Grinder Pump used in this case study had the following specs:
• GF series model 32GF22.2: 44 GPM @ 108’ TDH max
• 1.25” NPT discharge w/elbow
• Semi-open impeller
• 55-60 Rockwell C hardness cutter and cutter ring
• FC 200 cast-iron construction
• 316SS hardware
• 3-HP, 230-460/3/60 motor
• 30’ control cable
• Double mechanical seal
Lower – carbon ceramic
Upper – silicon carbide/silicon carbide

Whatever it takes: ABOVE AND BEYOND FOR EMERGENCY REPLACEMENT PUMP

R. A. Ross rep’s “Never give up”
attitude saves client from weeks
of downtime and loss of money.

We had a customer with a Dean R4140 2x3x8.5 hot oil pump that was down and they were faced with an 8-10 week leadtime. The factory did not have castings for one of the parts they needed to repair their existing pump or for a replacement pump. With this pump down, part of the customer’s plant was down and costing them money minute by minute.

Knowing they needed a pump we started exploring options we had at our disposal. Our first option was to find another pump just like what they had. We tried several other Dean distributors to see if they had a pump in stock with no luck. Next we tried a few of the refurbishing dealers we work with to see if anyone had a rebuilt pump; no luck. Facing a third strike we turned
back to Dean and the RA Series Air Cooled Hot Oil Pumps.

The Dean RA3000 series air cooled hot oil pumps are dimensionally interchangeable with with the R4140 series pump piping and baseplate dimensions envelope. Furthermore they share the same hydraulic characteristics meaning they would provide the same flow and pressure as the existing pump.

The last hurdle in being able to offer the RA3000 pump is that it will not handle as high of a temperature as the R4140. Luckily the customer’s process was still well within the limits of the RA3000.

After going back to Dean to find they did not have a pump in stock or the ability to expedite one, we again turned to some of our other fellow Dean distributors. The RA3000 series pumps are a very common pump for OEM’s to use in hot oil system packages and are more commonly stocked by Dean distributors. After several calls we found a fellow distributor that had one in stock and agreed to help us out. We worked quickly with the customer to get an order placed and have the pump shipped overnight to get them back up and running.

“ Brad, you have gone above and beyond!”

The pump arrived and was installed quickly since it was a drop in getting them back on line with minimal downtime.

The R. A. Ross team’s creative skills solve complex problem with innovative solution

Situation/Solution: A large oil company requested a Blackmer pump that would be used for “proving” gasoline, ethanol, diesel and biodiesel at several of their facilities. The specifications were listed as seen in the chart to the left.

The Ductile Iron Blackmer X4B 4” Sliding Vane Pump with Carbon vs. Iron. Viton mechanical seals met the specifications ideally running at 57% of maximum speed (which would give them long service life). The pumps would be coupled to Blackmer 5.77 to 1 HRB helical gear reducers with a 2.24 to 1 service factor for cool running operation and long reducer life. A 15 HP motor gave them more than sufficient safety margin.

Our job is to help keep you up and running.

R. A. Ross & Associates offers customers over 100 years combined experience with pumps and repairs.

 

THE PROJECT SPECS:

Blackmer X4B Sliding Vane Pump assembly:
•Ductile iron construction
•Duravane vanes

•Carbon vs. Iron mechanical seals
•Standard internal relive valve w/35-50psi spring
•4” NPT flange connections
•HRB 5.77:1 reducer to produce approx. 303rpm w/1750rpm motor
•15hp 3/60/230-460/1750 rpm Explosion Proof motor
•Formed steel base plate, couplings and guards

Trailer packing and control panel:
•5’ x 8’ 2990# capacity single axle utility trailer w/DOT approved lighting
•Tongue jack w/foot plate / tongue accepts 2” ball
•Jack on each rear corner for leveling/stability
•12ga. Treadplate steel floor
•2 – Wheel chock set and tool box w/lid and closure for storage
•Trailer dolly for movement of package by hand

RESULT:

Our client is very satisfied with not only our solution, but with the fact that we finished the project on time and under budget, and has ordered additional units from us.

Blackmer pumps are chosen in many cases as they are much “greener” (more energy efficient) than internal gear pumps. Blackmer vane pumps maintain their efficiency and flow even as the vanes wear where gear pumps start
losing flow and energy with any wear that occurs. The chart below shows the difference:


Blackmer X-Sliding Vane Pump typical applications:
Clean, non-corrosive industrial liquids and petroleum products, including fuel oils, lube oils, jet fuels, gasoline, edible oils, and a variety of solvents and thinners such as esters, ketones, naphtha’s, ethers, amines, aromatics, alcohol’s, terpenes, glycol’s and many other similar liquids.

Features and Benefits:
• Unique sliding-vane pump design self-adjusts for wear to maintain flow rates.
• Excellent self-priming and dry run capabilities.
• Blackmer mechanical seal and ball bearing construction provide maximum reliability.
• Symmetrical bearing support assures even loading and wear for long life.
• Adjustable relief valve protects pump against excessive pressures.
• External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk.
•Easy maintenance: vanes can be easily replaced without removing the pump from the piping system.

How Blackmer’s sliding vane action works

Blackmer’s positive displacement rotary pumps utilizing their unique sliding vane design offers the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost. Also, the high suction lift capability of these pumps makes them especially suitable for pumping from underground tanks, bulk plant service and aircraft refueling

Refinery uses Dean and ASI for sodium hydrogen sulfide (NaHS) application
Problem: Pump seals leak sodium hydrogen sulfide into atmosphere.

Solution: The raw gas sulfur knockout process at a local refinery produces sodium hydrogen sulfide (NaHS) and must be circulated through the tank to keep particles in suspension. The particulate can be anywhere from the size of a grain of sand to the size of a pencil eraser. Luckily the particles are easily deformable with the consistency of wet cereal making a centrifugal pump an acceptable means of transfer. The problem is the sealing of the pump. The product has a tendency to crystallize and the customer did not want any leakage of the product to atmosphere. For our application the customer chose to use a double seal with an API Plan 53 setup. In this setup a pressurized seal pot is used to isolate the product from atmosphere. The barrier fluid is contained in a seal pot which is pressurized to a higher pressure than the pump seal chamber. Barrier fluid must be compatible with the process fluid as there will always be some leakage of the barrier fluid into the process fluid.
