Fire Pumps

B Marsden

Going back to the 1940’s and 1950’s the fire pumps were either rope or crank start. Rope start pumps could be very difficult to start when weather conditions were extremely hot, causing a pump operator to become quite flustered, to put it mildly, with the constant rewinding and pulling on the rope to get the motor to start. This problem was evident with the rope start motors on the 7HP Howard Grascos and Wisconsin GAAM pumps installed on the Bedford RLHC tankers during the 1960’s. The Howard motors would eventually become obsolete, and be replaced over time by the modified 7HP Wisconsin GAAM. (Fig.1)

During this period the FCV Fire Protection Workshop converted the 7HP Wisconsin GAAM engines to electric start by installing a ring gear assembly to the output shaft of the motor, and a starter motor to a mounting plate bolted to the engine housing. Power was provided from the Bedford tanker battery. This was the start of a program of fire equipment improvements that would greatly assist the tanker operators and fireline personnel. (Fig.2) It still took until the 1980’s to completely remove all the rope start Howard Grazcos pumps from service.

By the late 1960’s a standardisation program was underway that would allow a pump, whether it be for a small, medium or large tanker, or for quick filling, to be replaced with little effort should a failure occur.

Each pump, depending on its role, was fitted with a standardised base frame. Each large tanker and trailed water tank were fitted with a mounting frame that allowed each pump to be easily supported and locked down. Note: Slip on fire fighting assembly’s had not yet been developed. Pump connections were standardised with loose nut and tail fittings to assist a timely replacement operation.

In 1983 the 7HP Wisconsin motors were replaced by a more efficient and smooth running 10HP electric start Honda G400 petrol engine, coupled to the GAAM 30B pump. The following year the Honda G400 and a more efficient GAAM MK 100-GX pump providing greater flow and pressure was introduced. (Fig.3)

In 1994 the large tanker pumps were again upgraded to a GAAM MK125 pump close coupled to a 17.7HP Ruggerini diesel engine. Petrol powered tankers had now been replaced with diesel powered Isuzu and Mercedes vehicles, that provided an option to ensure that the Ruggerini pump would always have fuel. This was achieved by installing a sealed header tank above the Ruggerini pump, and connecting the Isuzu engine diesel return line via the header tank to the main Isuzu diesel tank. The header tank was then plumbed into the Ruggerini fuel inlet port. The diesel pump now had a constant fuel supply alleviating the necessity to continually check the pump fuel tank level. (Fig.4)

During the 1990’s the Altona Fire Equipment Centre developed a Pump Water Flow Control Mechanism for operation with the large tanker pumps. The flow control mechanism would automatically return the pump to idle when the delivery hose was shut off. This eliminated the need for a tanker operator to climb up on the deck to manually return the pump to idle. Similarly the flow control mechanism allowed the water flow to commence and increase the motor revs when the delivery hose nozzle was again turned on. The introduction of this technology reduced engine and pump damage through constant over revving, and unnecessary inline pressure on hose couplings and pump seals when the water delivery line is closed.

Considering the reliability and benefits provided by the Water Flow Control technology all 3" trolley mounted firebombing base transfer pumps were systematically upgraded. (Fig.5)

Due to the pressures provided by many of the pumps being operated from both tankers and trailer pumps, the Pacific Marine style pump was not replaced when it was auctioned off during the 1980’s. However, the ever reliable Wajax Mk3 remained a fire cache item ready to be called on should a specific need for a small transportable pressure pump arise. The Wajax Mk3 has been in circulation since the 1950’s, and through that time has undergone several upgrades to keep pace with current trends.

The smaller universal water pumps operated over the past 60 years have included the 1.5" Rex, Alcon, Alpha and Davey Firefighter pumps.

The single impellor Davey GX160 pump close coupled to a 5.5HP Honda motor has been one of the most popular small pumps operated by forestry workers during this period. They have filled the role of a utility tool for washing out culverts and camp site floors and, with an output of 450LPM, are installed as a backup pump on the large tanker fleet. There have been over 2000 Davey Firefighters fitted to the small tankers manufactured since the 1980’s. (Fig.6)

Forests Commission Pump School

The Victorian Forests Commission held a pump school at the Glenmaggie Weir on Wednesday. Object of this school was to familiarise all Commission employees with the working of the different types of units used.

It was attended by all Forests Commission Officers and gangs from Heyfield and neighbouring districts.

The officer in charge of the Heyfield District, Mr Val Cleary, was in charge of the school, and representatives of Heyfield mills were invited to attend the morning session. The Newlands Lumber Co., Licola Sawmilling Co., and JW Porta and Sons were represented. The afternoon session was utilized by Commission employees to familiarise themselves with the starting and operating of the pumps.

Barry Marsden

Barry grew up in East Gippsland, Victoria, in the small timber town of Cabbage Tree which consisted of five sawmills (where his father was a bulldozer operator for one of the mills), a local store and a primary school. The family moved to Orbost in about 1955 when he and his two sisters commenced high school.

Following high school Barry completed an apprenticeship as a motor mechanic at a local garage, Merlin Motors, a respected family business.

In 1966 he joined the Forests Commission at Orbost, initially working with the crew on the Errinundra Plateau road construction program where he was trained in the use of explosives to clear trees and rocks from the proposed road line.

Following a vehicle accident in late 1966, Barry took over the repair and maintenance of the Commission’s vehicle fleet at Orbost. In 1969 he married and transferred to Bairnsdale from where he maintained the region’s heavy plant equipment from a base at Bruthen.

So that he would have experience in the operation and procedures of a large workshop, in 1970 Barry was transferred to the Commission’s main plant engineers’ workshop in Newport, Melbourne, and in 1971 he joined the Commission’s Transport Branch as a Technical Assistant to the Transport Officer.

In 1972 Barry became Assistant Fire Equipment Development Officer at the Forests Commission’s Fire Equipment Development Centre at Altona and was promoted to Manager in 1983.

In 1988 he was sent to Canada on a six-week study tour hosted by Aviation Company - Conair to seek out alternative fire equipment technology and innovative ideas to improve on that which was in use by the Department in Victoria.

In 1990, with increasing interest in the use of Class A foams for quelling fire, Barry represented Victorian land management agencies on the North West Coordinating Group Fire Equipment Working Team’s Task Group for International/Interagency Foams and Application Systems. From 1992, he represented the Department at annual forums of the National Fire Equipment Development Officers Group whose aim was to co-ordinate the research, development and supply of fire equipment by member organisations of Fire Control Officers Group.

Barry represented Australia at the International Fire Equipment Working Group and Fire Equipment Working Team biannual joint meetings to share current trends, innovation and experiences in firefighting. He continued to participate at both National and International fire equipment forums until his retirement in 2010.

Hosted by the Overseas Projects Corporation in 1995, Barry was sent to Western Samoa to train local fire personnel in the use of fire fighting equipment purchased from the Department, and the operation of Class A foam technology.

In 2000 and 2002 he was part of an Australian contingent of fire fighters who travelled to the USA to assist American fire crews combatting large forest fires during extremely dry conditions. Queen’s Birthday Honours saw Barry awarded an AFSM in 1988 for distinguished service as a member of the Victorian Fire Services, and an Order of Australia (AM) in 2012 for Service to Public Administration in Victoria in the Fire and Emergency Services Sector and to the Development of Innovative Fire Fighting Equipment and Technologies.
